But looking up at Jimmy now he saw dry eyes and a quizzical if impatient phizz. Turning the other way, he saw Danny gazing distractedly at the White Tower. ... "Before you embark on a new life overseas, assuming that is your fate," Jack said, "find Eliza and tell her she is my true love." And then he jerked the chains loose from the restraining grip of first Jimmy, then Danny. He leaned forward, pushed off against the rail with both feet, and launched himself into space above London. His cloak spread in the wind of his flight like the wings of an eagle, revealing, to anyone who might be gazing up into the sky, a lining made from cloth-of-gold that glistered in the rays of the setting sun like the chariot of Apollo.

You can see it now, with nicely HTMLized documentation, at: http://search.cpan.org/dist/Muldis-DB/ This is the first formal release of Muldis::DB, which began development last year (under the temporary name of "QDRDBMS") as a rewrite of my previously released but never functional "Rosetta" project. Muldis::DB is implemented as a library or open-ended framework for use by larger frameworks or applications, and is a DBMS resource to them. This project comes in twin Perl 5 and Perl 6 versions which are feature identical; the former is for use in today's systems, and the latter is for longer term use; if there is a case for doing so, some parts may be moved to other languages later such as C. The equivalent Perl 6 version of Muldis::DB to the CPAN release is bundled with the "Pugs" ( http://www.pugscode.org/ ) implementation of Perl 6, and its release to CPAN follows Pugs' schedule. Meanwhile, you can see it in the ext/Muldis-DB/ sub-directory of Pugs' version control. With both initial versions, Muldis::DB has zero external dependencies but for Perl/Pugs itself and what is bundled with it; this should ease installation. If you want to read all the Muldis::DB documentation that exists now, I recommend doing so in this order: 1. http://search.cpan.org/src/DUNCAND/Muldis-DB-0.0.0/README 2.

(opt) http://search.cpan.org/src/DUNCAND/Muldis-DB-0.0.0/TODO 11. (opt) anything else The "README" file above includes the urls of the public version control systems that host the development of Muldis::DB. The Perl 5 version is hosted in a public GIT repository hosted by Sam "Mugwump" Vilain, for which I am thankful. The Perl 6 version is hosted in the same public Subversion repository as Pugs. Muldis::DB defines and implements a computationally complete programming language with integrated relational database functionality. It is an open-ended framework with a separate programmatic API and pluggable implementing engines, one of which is bundled with the core so it works out of the box. The framework is intentionally similar to the DBI framework in organization. Muldis::DB implements a D language (named "Muldis D") as defined by Hugh Darwen and Chris Date, and presents a superior interface for working with the relational model of data, contrasted with SQL. Anyone familiar with SQL or the relational model, or just programming in general, should find it easy to learn. One general strength of Muldis D (truly relational) over SQL (quasi-relational) is that there is next to no object-relational impedence mismatch since the true relational model can natively represent user-defined complex data type structures, constraints, and operators; there is no need for "object-relational mappers", except for their role in tighter host language integration. Another general strength of Muldis D is that any arbitrary business rules can be cleanly expressed as constraints on a database, so it is easier to trust a database to ensure its data state or transitions are always conformant to business rules, without hoisting such integrity matters to the application, where it is a lot more difficult to do it reliably. Since a D language can represent anything, a SQL database and/or SQL features can also be emulated over one, which helps with legacy migration; similarly, as much as is possible, existing SQL engines can be used to implement Muldis DB over top of, in which case Muldis DB acts as a SQL generator to access pre-existing databases in new applications. Conceptually speaking, Muldis::DB is either a replacement for DBI, or a replacement for any SQL DBMS itself, depending on how you use it; out of the box it replaces both, but plug-in bridges can be made that bridge to either. Taking the Perl 6 development process as a model, Muldis D has an authoritative human-readable design document (the Language.pod file), which is analagous to the Perl 6 Synopsis documents, and one or more separate conforming implementations (the other files). It is very feasible that Muldis D could have multiple implementations, over any languages, besides the 2 (Perl 5 and Perl 6) that exist now. More information is in the Muldis::DB documentation. I would probably like to say that Muldis::DB would be a panacea to all your database ills, but instead I see it more like Muldis::DB should provide a more solid skeleton on which to build the solutions to all your database ills than are any other solutions. I will contribute to the solutions as best I can. Several public email-based forums for Muldis::DB now exist (with public archives), all of which you can reach via http://mm.DarrenDuncan.net/mailman/listinfo (note that Mailman's monthly password reminder email is turned off). There are currently 3, for 'announce', 'devel', 'users', modelled after the main lists for DBI. I invite you to join one or more of these lists (if you haven't already), to better facilitate discussion, support, and group development. As of this version-zero release, Muldis-DB is officially in pre-alpha development status. A lot of documentation and functionality is present, but a lot isn't. What is mostly done is the higher level documentation plus an alpha-quality but fundamentally stable public API implementation. What is mostly undone is the reference engine implementation, the test suite, and documentation of the API details. What is already present should be sufficient to begin study of Muldis-DB such that it can actually be put to use within the next few weeks or months as Muldis-DB is fleshed out. Also, it should be possible now to start writing code that uses or extends it. To conclude, I would be very greatful for any and all kinds of assistence with the Muldis::DB framework that you can provide, which includes building or sponsoring features and extensions. Probably the very first kind of help that I could use the most is with writing cookbook-type examples of using Muldis::DB and/or FAQ documents. This both helps people learn how to use it in an effective manner, and also helps flesh out deficiencies in Muldis::DB. Both the "how do I define this kind of database" variety and "how do I express this SQL in Muldis D" variety are helpful. These examples would be released as a Muldis::DB::Cookbook distribution. I also welcome general feedback, constructive criticism, suggestions, corrections, and questions. Note that I prefer any responses to happen on-list, or that you sign up to and post to a muldis-db list (only list subscribers may post), so that that and any replies can be for the group's benefit, and to save me from repeating the same answers ad nauseum. Unless the response is not suitable for public discourse, in which case, sure, go private email; ditto if you're not sure about appropriateness. Thank you in advance. -- Darren Duncan http://www.nntp.perl.org/group/perl.perl6.announce/2007/06/msg570.html Thu, 21 Jun 2007 12:04:57 +0000 Parrot 0.4.13 "Clifton" Released by Allison Randal On behalf of the Parrot team, I'm proud to announce Parrot 0.4.13 "Clifton."

The note said, "I am coming," and it was signed by me. ... The sun hung low on my left and the winds bellied the sails and propelled me onward. I cursed once and then laughed. I was free and I was running, but I had made it this far. I now had the chance I'd wanted all along. A black bird of my desire came and sat on my left shoulder, and I wrote a note and tied it to its leg and sent it off into the west. It said, "Eric--I'll be back," and it was signed: "Corwin, Lord of Amber." A demon wind propelled me east of the sun. -- Nine Princes in Amber, Roger Zelazny On behalf of the Parrot team, I'm proud to announce Parrot 0.4.12 "Of the Caribbean."

Enjoy! http://www.nntp.perl.org/group/perl.perl6.announce/2007/05/msg568.html Tue, 15 May 2007 21:18:12 +0000 Weekly Perl 6 mailing list summary for 08-14 April, 2007 by Ann Barcomb This week on the Perl 6 mailing lists "The current pugs implementation is just translating to the old form underneath, so it's not surprising it's a bit off. That's the sort of thing that happens when the language designer gives the language implementor whiplash. However, I rather suspect the interpersonal metaphorical meaning was lost on the physicist/comic who decided that the 3rd derivative of position should be called 'jerk'. :)" -- Larry Wall, in 'What should file test operators return? <http://xrl.us/vrq4>' Language Re: Synopsis 26 <http://xrl.us/vrny> Earlier, Thom Boyer responded to Damian Conway's post from November which thanked people for offering feedback on the first draft. Thom said that he had been unable to find the XHTML version of S26 and wondered if it was available. Jerry Gay replied that there wasn't a pod parser available yet. Damian responded with the requested file, and said he still hoped to finish the Pod6 parser but he wasn't sure when he would have time. Ãvar ArnfjÃ¶rÃ° Bjarmason asked if Damian could post the code he currently has, so that others could work on it. This week, Damian responded by uploading `Perl6::Perldoc` to CPAN. Ãvar and Damian worked to improve the test suite. Does =$*ARGS work? <http://xrl.us/vrq2> brian d foy is working on 'Learning Perl 6' and had some questions about for the I/O chapter. He saw that `while(<>){...}` became `for=$*ARGS{...}` but noted this didn't work in Pugs. He wondered if it was a documentation error or an implementation error. Moritz Lenz mused about why it wasn't `=@*ARGS` but couldn't answer brian's question. brian replied that `$*ARGS` is a filehandle, not a list of files. David Vergin remarked that there was a typo in S28 and corrected it. using <sp> space in character classes <http://xrl.us/vrq3> Brad Bowman noted that S05 lists `sp` under named assertions but doesn't explicitly mention it in the character class section. He wondered if it could be used in that way. Larry Wall replied that it could be, but it needs to be generalized. What should file test operators return? <http://xrl.us/vrq4> brian d foy noted that file test operators return false or the filename, when he would have expected a true. He wanted to update S16 to clarify the situation. Later Larry Wall said he would attempt to clarify S03. Moritz Lenz and Damian Conway had some suggestions for the syntax in brian's code. Juerd Waalboer and Larry Wall also joined the conversation on the subject of giving printf a boolean output template. They found it too specific. Brandon S. Allbery noted that Pugs does not implemented the specification as it is documented. He thought junction types aren't completely ready. John Macdonald and Mark J. Reed also contributed to the thread. Parrot Porters remove_method vtable? <http://xrl.us/vrq8> Jonathan Worthington noted that PDD 15 describes both add and remove vtable methods for attributes, parents and roles, but only `add_method` exists for methods. He wondered if `remove_method` should also exist. Allison Randal went ahead and added it, after a bit of internal debate. [perl #42332] [TODO]: Eliminate t/tools/ops2pmutils/testlib/Capture.pm <http://xrl.us/vrq9> Ticket [perl #42332] <http://xrl.us/vtwx>, by James Keenan, asked for some subroutines to be moved into `lib/Parrot`. This was fixed in r18040. [perl #42334] PGE compiler faults out "set_integer_keyed() not implemented in class 'Undef'" <http://xrl.us/vrra> In ticket [perl #42334] <http://xrl.us/vtwy>, Jim McKim reported a fault when compiling an example grammar. Patrick R. Michaud replied that there was a problem with the cut operator not being applied to a particular term. He saw it as a request to improve the error message when a cut token is applied to a null term. inspect and inspect_str from PIR <http://xrl.us/vrrb> Jonathan Worthington reported that he had implemented the `inspect_str` and `inspect` vtable methods for the Class PMC. He had a question about the implementation. Allison Randal replied that she had added an opcode `inspect` and a method `inspect` on roles and classes to the PDD. [perl #42336] segfault happens with 'parrot --pre-process-only' <http://xrl.us/vrrc> Jim McKim reported a segmentation fault when Parrot is invoked with `-E`. This was ticket [perl #42336] <http://xrl.us/vtwz>. [perl #42337] [PATCH]: Configure.pl: Refactor list of steps into Parrot::Configure::Step::List <http://xrl.us/vrrd> James Keenan created ticket [perl #42337] <http://xrl.us/vtw2> to paste a patch which moved some of `Configure.pl`'s functionality (listing steps in the configuration process) to a module. This was applied as r18157 and r18158. [perl #42339] [CAGE] Test Valid and Invalid Parrot Flags <http://xrl.us/vrre> chromatic reported that there are no tests for Parrot's response to invalid command-line arguments. He suggested adding some in ticket [perl #42339] <http://xrl.us/vtw3>. James Keenan said that he had recently added a test of this sort. chromatic clarified: he meant command-line arguments to the Parrot executable, not to `Configure.pl`. [perl #42349] [TODO] dotnet - fix various ops for 64 bit architectures <http://xrl.us/vrrf> Paul Cochrane made a note that some ops need to be fixed for 64-bit architectures in ticket [perl #42349] <http://xrl.us/vtw4>. [perl #42352] [TODO] fix or remove strange TODO item in hash() op <http://xrl.us/vrrh> In ticket [perl #42352] <http://xrl.us/vtw5>, Paul Cochrane noted that `src/ops/pmc.ops` has a todo item marked 'XXX' which lacks an explanation of what the problem is. [perl #42359] [PATCH] Assorted cleanups - part III (Intel C++) <http://xrl.us/vrrn> Steve Peters submitted a patch in ticket [perl #42359] <http://xrl.us/vtw6>. This cleans up some warnings when compiling Parrot with Intel C++. chromatic got some warnings when running the patch. He made some changes to the patch and sent it in. Steve said he would need to look into it further. [perl #42360] [TODO]: Unit tests for Parrot::Revision <http://xrl.us/vrro> In ticket [perl #42360] <http://xrl.us/vtw7>, James Keenan reported that `lib/Parrot/Revision.pm` has no unit tests. [perl #42362] [TODO]: Unit tests for modules used during configuration <http://xrl.us/vrrp> James Keenan indicated that there is a considerable amount of code in the `config/` tree which isn't covered by tests. He requested some unit tests in ticket [perl #42362] <http://xrl.us/vtw8>. [perl #42371] [TODO] check if object.can(method) in callmethodcc() op <http://xrl.us/vrrr> Paul Cochrane created ticket [perl #42371] <http://xrl.us/vtw9> for a todo item in `src/ops/objects.ops`. Jonathan Worthington thought that it was unnecessary and suggested removing the comment. Allison Randal agreed. JSON won't make test <http://xrl.us/vrr3> Klaas-Jan Stol submited a patch which alters `json.in` to make it pass `nmake test`. It was committed as r18063. [perl #42383] [TODO] imcc - if frame->s.file was allocated free it <http://xrl.us/vrr5> Paul Cochrane created a number of RT tickets based upon 'todo' messages in the code source: * `compilers/imcc/imcc.l` - [perl #42382] <http://xrl.us/vtxa>, [perl #42383] <http://xrl.us/vtxb>, [perl #42384] <http://xrl.us/vtxc> * `compilers/imcc/imcc.y` - [perl #42385] <http://xrl.us/vtxd> * `languages/regex/lib/Regex/Grammar.y` - [perl #42393] <http://xrl.us/vtxe> * `src/opts/pics.ops` - [perl #42353] <http://xrl.us/vtxf>, [perl #42354] <http://xrl.us/vtxg>, [perl #42355] <http://xrl.us/vtxi>, [perl #42356] <http://xrl.us/vtxj> * `src/ops/pmc.ops` - [perl #42350] <http://xrl.us/vtxk> * `src/ops/stack.ops` - [perl #42369] <http://xrl.us/vtxm> * `src/ops/object.ops` - [perl #2372] <http://xrl.us/vtxn> * `src/ops/io.ops` - [perl #42373] <http://xrl.us/vtxo>, [perl #42374] <http://xrl.us/vtxp> * `src/ops/experimental.ops` - [perl #42375] <http://xrl.us/vtxq>, [perl #42376] <http://xrl.us/vtxr> * `src/ops/debug.ops` - [perl #42377] <http://xrl.us/vtxs>, [perl #42378] <http://xrl.us/vtxt>, [perl #42379] <http://xrl.us/vtxv> * `src/ops/core.ops` - [perl #42381] <http://xrl.us/vtxw> Parrot Bug Summary <http://xrl.us/vrr8> Jerry Gay remarked that the Parrot ticket queue is growing every week; there are currently more than 500 tickets, many of them unclassified by type. He asked for volunteers to help make the queue more manageable. In another thread, which was part of ticket [perl #41858] <http://xrl.us/vk9x>, Mark Glines said he had taken on the task of making a reasonable set of rules for splint. He ran into several problems. Paul Cochrane tried to answer the questions as best as he could. The great "class" variable renaming <http://xrl.us/vrsa> Steve Peters has had problems with the use of 'class' as a variable name in `struct_vtable`. This needs to change for his compatibility work to progress further. He suggested `pmc_class` as an alternative. Klaas-Jan Stol remarked that he thought the word `namespace` should also be used carefully. Class/Role namespace links <http://xrl.us/vrsb> Jonathan Worthington began working on the association between classes and namespaces specified in PDD15. He had some questions, which Allison Randal answered. [perl #42406] [PATCH] improper null testing in Parrot_instantiate_object <http://xrl.us/vrsd> Alek Storm reported in ticket [perl #42406] <http://xrl.us/vtxx> that he had a patch to fix a bug in which the `init` vtable method override is called instead of `init_pmc`. After one week he wondered why no action had been taken. [svn:parrot-pdd] r18096 - trunk/docs/pdds <http://xrl.us/vrse> A commit by Allison Randal added opcodes and methods for 'inspect' to Objects PDD. [perl #42407] [PATCH] refactor vtable overriding, delegate.c generation <http://xrl.us/vrsf> In ticket [perl #42407] <http://xrl.us/vtxy>, Alek Storm submitted a patch which refactors and optimizes methods involved in vtable overriding. [perl #42411] [PARTIALPATCH] Building a 32bit parrot on freebsd under amd64 fails. <http://xrl.us/vrsj> Joshua Isom created ticket [perl #42411] <http://xrl.us/vtxz> to submit a patch which allows Parrot to be configured for 32-bits on a 64-bit machine. This does not completely fix the problem. [perl #42412] Configure.pl things =no is true <http://xrl.us/vrsk> Joshua Isom thought that configure should treat `--foo=no` is false instead of true. He reported this in ticket [perl #42412] <http://xrl.us/vtx2>. Severe error <http://xrl.us/vrsm> Christian Aperghis-Tramoni reported an error he saw when compiling Parrot on Linux. call for help: pdd15 implementation <http://xrl.us/vrsn> Jerry Gay highlighted the implementation of PDD 15 as a key goal for the 0.4.11 release (which has since taken place). He suggested that people could help by reviewing docs/code/tests. modifying classes after they're instantiated <http://xrl.us/vrso> Allison Randal began by remarking that Jonathan Worthington had raised the question of the strategy for safely changing classes which already have instantiated objects. She offered a few alternatives. Both Leopold Toetsch and Allison thought her fourth suggestion was the best one. Alek Storm liked it too, but had another option. There was some further discussion about the best implementation, with Bob Rogers also joining in. [perl #42427] [CAGE] cleanup perlcritic errors <http://xrl.us/vrsp> Jerry Gay noted that many tests fail in `t/codingstd/perlcritic.t`. In ticket [perl #42427] <http://xrl.us/vtx3> he expressed his hope that these things could be addressed before the next release. [perl #42429] [BUG]: docs/submission.pod: Confusing use of term 'test' <http://xrl.us/vrsq> James Keenan reported that he found instances of the word 'test' confusing in `docs/submission.pod`. He asked for clarification in ticket [perl #42429] <http://xrl.us/vtx4>. [perl #42430] [PATCH] make :vtable imply :method <http://xrl.us/vrsr> Alek Storm created ticket [perl #42430] <http://xrl.us/vtx5>. This contained a patch which makes the `:vtable` sub pragma imply the `:method` pragma. What followed was a long discussion on why someone might want to set `:vtable` without setting `:method`. Alek, chromatic, and Allison Randal contributed to this deeply nested thread. [ANNOUNCE] Hackathon Toronto, Saturday April 28 <http://xrl.us/vrss> James Keenan announced a spur-of-the moment hackathon in Toronto. It was held on Saturday, April 28th. [Proposed PATCH] Change libparrot Names and Locations <http://xrl.us/vrst> Ron Blaschke proposed a patch to change the libparrot names and locations for Windows, which he included in his message. Jerry Gay added his comments, and noted that it is nice if tests are included. There was some further discussion on how to improve the patch. Limiting Exported Symbols on GCC <http://xrl.us/vrsu> Ron Blaschke kicked off this thread by wondering if there was a feature to limit exported symbols with GCC. Steve Peters was concerned about adding GCC features to Parrot, as this could break compatibility with other compilers. Nicholas Clark remarked that Perl 5 has been successful with using flag data in `embed.fnc` and generating annotated headers automatically. Jerry Gay agreed with Nicholas and suggested that if a function isn't meant for public consumption, it shouldn't be available. Joshua Isom suggested that people can use whatever functions they want, but if they aren't documented, they are likely to be broken in future releases. Joshua Isom was concerned that it had been a long time since there had been failure-free smokes, and people were becoming accustomed to test failures. Joshua Hoblitt and nahoo82 also contributed to the thread. [perl #42474] [PATCH] Remove dangling enum commas <http://xrl.us/vrsv> Steve Peters submitted a patch in ticket [perl #42474] <http://xrl.us/vtx6> which removes dangling commas in enum lists. It was applied as r18175. [perl #42475] [PATCH] Change asm() to __asm__() <http://xrl.us/vrsw> In ticket [perl #42475] <http://xrl.us/vtx7>, Steve Peters supplied a patch to help Parrot compile with `-ansi -pedantic`. It was applied as r18176. Bug Day: Saturday, 14 April 2007 <http://xrl.us/vrsx> Matt Diephouse announced that Saturday 14 April was a bug day to prepare for the 0.4.11 release. This release was made on 17 April. [perl #41894] segfault happens when invoking poll op <http://xrl.us/vrsy> Earlier, Jim McKim created ticket [perl #41894] <http://xrl.us/vtcf> to report a segmentation fault. Will Coleda offered a patch, which Nuno Carvalho applied. Jonathan Worthington reported that the patch broke the build for Win32. He committed a correction in r18187. Joshua Isom suggested an alternative way of addressing the problem. Compiler request for a few Pugs parser updates <http://xrl.us/vrsz> Darren Duncan asked for a few features to be added to the Pugs parser. There were three requests in total, which Darren hoped could be easily implemented by the right people. pugs: aborting smoke tests <http://xrl.us/vrs2> Moritz Lenz reported being unable to do a `make smoke` for the last few weeks. Larry Wall thought that the problem looked like a resource exhaustion or lockup, possibly related to embedded/tunneled Perl 5. He asked for more output, which Moritz supplied. Agent Zhang pointed to a post by chromatic which he thought might relate to the solution. interactive pugs fails in safe mode <http://xrl.us/vrs3> Wim Vanderbauwhede reported failures with interactive Pugs when `PUGS_SAFEMODE` is true.

More information about his proposal can be found in the grant application text. Details about the microgrant application procedure <http://xrl.us/vtgf> are available for those interested in submitting a proposal. [S03] typo <http://xrl.us/vrpe> Jonathan Lang submitted a patch which corrects a typo in S03. [S03] Range Semantics <http://xrl.us/vrpf> Jonathan Lang suggested a change to S03 which was inspired by the new array indexing syntax from S09. This would make Ranges in an array index a natural outgrowth of the standard Range semantics. [S03] Negation metaoperator <http://xrl.us/vrpg> Jonathan Lang had a proposal to generalize the negated relational operators to apply to any infix operator which returns a boolean. Larry Wall rejected the suggestion because the relationals Jonathan named are typed to return Any, not Bool. Parrot Porters [perl #39934] [PATCH] Make disassemble useful. <http://xrl.us/vrph> Kevin Tew created ticket [perl #39934] <http://xrl.us/vtqj> with a patch and requested feedback...back in July of 2006. Paul Cochrane applied it as r17922 on April 1st. [perl #41774] [BUG]: Failures in 5 tests during 'make test'; partially patched <http://xrl.us/vrpj> James Keenan created ticket [perl #41774] <http://xrl.us/vtqk> to report errors on 5 different tests. Later he closed the ticket because the failing tests were identified as part of ongoing work and the tests were no longer failing. [perl #41860] [CAGE] Run Parrot under Coverity Prevent <http://xrl.us/vrpk> Paul Cochrane wanted to get Coverity to run Prevent on Parrot. This was ticket [perl #41860] <http://xrl.us/vk9z>. More recently, Paul reported that he'd received a reply stating that Parrot could certainly be added, but that no date estimate was available at the moment. Syntax for Constructing new Objects (and classes?) <http://xrl.us/vror> This thread began with Klaas-Jan Stol asking about the syntax for constructing new objects because he thought that it was going to be changed. Allison Randal replied with examples of the two proposals for the new syntax. This led Alek Storm to ask if `new()` would be a vtable method or a PCCMETHOD. Jonathan Worthington confirmed that it is a PCCMETHOD. Allison elaborated that it is a class method. More recently, Alek replied that he thought that `new` should be kept an opcode, and `new()` should be a vtable method which is called from inside the `new` opcode. Jonathan Worthington was confused by Alek's proposal. He suggested making BaseClass implement all the vtable variants of a method, and Class can inherit from it and provide a sane interface. Alek thought that Jonathan's suggestion was similar to one he had made in [perl #41619] <http://xrl.us/vev4> but that Jonathan's explanation was superior. Allison also added her thoughts to this subthread. In the main thread, Jonathan proposed deprecating the old syntax in the next release and removing support for it in the following release. Allison agreed to marking it as deprecated now. Joshua Isom wanted the dot syntax to still work so that tests wouldn't need to be rewritten. Allison explained that there were several reasons to remove constants for types and the class registry. compilers/pirc continued... <http://xrl.us/vrpm> Klaas-Jan Stol added a vtable to the parser in `compilers/pirc`. He proposed looking at the bcg project to see if it would fit in with `compilers/pirc`. Allison Randal thought it was worth exploring. [svn:parrot-pdd] r17907 - trunk/docs/pdds/draft <http://xrl.us/vrpn> A commit by Allison Randal integrated some questions and comments into the Objects PDD. Jonathan Worthington had a few comments, such as noting that `resolve` is sugar rather than something new, and that comments about offsets should go away. Allison noted that `resolve` is the preferred way of dealing with conflict resolution, and removed references to offsets. [perl #42261] Extensive failures in t/compilers/imcc/imcpasm/*.t and t/pmc/sub.t <http://xrl.us/vrpo> James Keenan posted some failures in `make test` in ticket [perl #42261] <http://xrl.us/vtqm>. Paul Cochrane reported that he was unable to replicate the failures with r17914 and asked James to check his revision. James looked into it further and concluded that the name of the sandbox was affecting the test results. He wondered if anyone could explain why that was happening. [svn:parrot-pdd] r17921 - trunk/docs/pdds <http://xrl.us/vrps> A commit by Paul Cochrane noted that Perl code with `__END__` or `__DATA__` blocks should not get an emacs or vim coda. Shawn M Moore suggested putting the coda at the top of the file, but Paul explained that this had been attempted but proved to be a poor solution for several reasons. [perl #42267] [CAGE] Work out how to encourage good editor-independent formatting habits <http://xrl.us/vrpt> Paul Cochrane created ticket [perl #42267] <http://xrl.us/vtqn> with the mission "Figure out how to encourage good formatting habits, without assuming that everyone uses emacs or vim, and with minimal clutter in our source code. Also write a coding standards test to codify this." [perl #39878] [CAGE] generated files with timezoneless times <http://xrl.us/vrpu> In ticket [perl #39878] <http://xrl.us/vtqo>, Will Coleda wanted tools which insert messages into generated files to include a timezone (which should always be UTC). Paul Cochrane said that generated files are checked for timestamps in `codingstd/gmt_utc.t` and that `config/init/defaults.pm` was updated in r17923 to pass the test. [perl #40861] [CAGE] - add a Perl::Critic policy to look for FIXME|TODO|XXX <http://xrl.us/vrpv> In ticket [perl #40861] <http://xrl.us/tc8k>, Paul Cochrane suggested adding a check for 'FIXME'/'TODO'/etc for the Perl source files, as there is currently only a check for the C files. This was done in r17925. Chris Dolan suggested using an existing Perl::Critic policy. Will Coleda asked if Andy Lester would accept a patch which would optionally permit 'TODO' comments which included ticket numbers and reject those which don't include ticket numbers? Andy replied that he didn't want to build exceptions, and proposed that people just write 'RT #12345' instead of 'TODO (#12345)'. Paul Cochrane agreed with this suggestion. Link'n'Load on Windows <http://xrl.us/vrpw> Ron Blaschke reported that he was looking into errors in linking and loading on Windows. With linking, there were some symbols which weren't exported. He planned to provide a patch to export them. To solve the loading issue, he wanted to change several files to include the full path. Current State of Building Parrot on Cygwin <http://xrl.us/vrpx> Ron Blaschke reminded the list that it is necessary to include the absolute path to `blib/lib` in the PATH environment variable to build on Cygwin. He also explained that some problems could be due to a file having Windows line endings. Eric Hanchrow wondered if it was possible to make Parrot less fussy about the line endings. Ron wanted to see that happen, but explained that his suggestions were workarounds until the problem was resolved. Steve Peters said he would be looking at how to improve the process. Ron described his thoughts in more detail in 'Link'n'Load on Windows <http://xrl.us/vrpw>.' chromatic asked if it was possible to pass flags to the linker to hint at the path, which is how the Linux version works. Ron thought that was handy, but hadn't seen something similar for Windows. [perl #42270] [PATCH]: Configure.pl: refactor options processing functionality <http://xrl.us/vrpz> In ticket [perl #42270] <http://xrl.us/vtqp>, James Keenan posted a patch which removes command-line option processing from `Configure.pl` and puts it in a library. This was done to make testing easier. The patch was applied as r17983 and 17984. [perl #42271] [PATCH] Borland C++ cleanups <http://xrl.us/vrp2> In ticket [perl #42271] <http://xrl.us/vtqq>, Steve Peters submitted a patch which cleans up Parrot for Borland C++ on Windows. This patch does not completely solve compilation issues because it seems to create new issues on Linux. chromatic applied it as r18134. Hash iteration question <http://xrl.us/vrp3> Jonathan Worthington showed two examples of iterating through a hash, and noted that in his first example you will only get the first key in the hash. He believes that the hash and iterator code are closely tied and isn't thread safe. Allison Randal replied that the significant differences are down to the iterator's `shift_pmc` throwing an exception if the key is -1, while `shift_string` doesn't check. She agreed that the code was excessively mixed and needed review. Leopold Toetsch added a further explanation on the implementation. PDD15: newclass <http://xrl.us/vrp4> Jonathan Worthington had a comment on PDD 15 and how it described the creation of a new class. He wondered about the implementation. Allison Randal replied that the `newclass` opcode will be a simple opcode. Jonathan implemented what Allison described and created a test for it as well. [perl #42072] [BUG]: pmc2c.pl: Does anyone (know how to) use the 'no-body' option? <http://xrl.us/vrp9> In ticket [perl #42072] <http://xrl.us/vtge>, James Keenan noted that nobody had spoken up in favor of retaining the `no-body` option. He said that he would take the ticket and assign the revisions to participants of the Perl Seminar Phalanx Phoneix project in NY. [perl #42279] [PATCH] Parrot cleanups - part 2 <http://xrl.us/vrqa> Steve Peters submitted a patch in ticket [perl #42279] <http://xrl.us/vtqr> which had some cleanups to make Parrot work better with different C compilers. It was applied as r17952. Paper on Software Patterns in Parrot <http://xrl.us/vrqb> Klaas-Jan Stol mentioned that he had recently taken a course on software patterns and co-authored a paper on patterns in Parrot, which he put on the wiki <http://xrl.us/vtqs>. [perl #42286] [CAGE]: Parrot::Pmc2c::PCCMETHOD constants should be autogenerated <http://xrl.us/vrqc> Jerry Gay noted that `lib/Parrot/Pmc2c/PCCMETHOD.pm` contains a number of constants, which should be generated during the configure process and included. Ticket [perl #42286] <http://xrl.us/vtqt> discusses this request. [perl #42287] [TODO] MMD needs to be in a PDD <http://xrl.us/vrqd> Jonathan Worthington wanted multi-method dispatch to be documented in one of the PDDs or get its own PDD. The request was made in ticket [perl #42287] <http://xrl.us/vtqu>. [perl #42292] [TODO] modify PCCMETHOD syntax to more closely match PDD03 <http://xrl.us/vrqe> In ticket [perl #42292] <http://xrl.us/vtqv>, Jerry Gay requested that the PCCMETHOD syntax be modified to put it in line with PDD 03. chromatic offered a patch. [svn ci] NCI methods now name-mangled <http://xrl.us/vrqf> Jonathan Worthington explained that he was starting to move class functionality into vtable methods, but ran into the issue that you cannot have a METHOD or PCCMETHOD with the same name as a vtable method. This is, however, required to implement the interface specified in PDD 15. He made some changes to get Parrot working again, which affected the Complex PMC. FranÃ§ois PERRAD reported that this change breaks Lua. Allison Randal observed the same thing, and asked Jonathan to either fix the problem for Lua or revert the change from the trunk. Jonathan apologized for breaking things and said that it was fixed in r17982. Leopold Toetsch suggested that perhaps language maintainers who are using "features" of Parrot could submit core tests for these features, so that this type of problem won't occur in the future. Joshua Isom thought this could be expanded to anyone using Parrot where a "feature" isn't tested. He proposed an open repository for tests. chromatic wondered if it was that difficult to mail in patches. Joshua offered some arguments in favor of it. chromatic parrotcode updates. <http://xrl.us/vrqg> Will Coleda solicited for suggestions concerning parrotcode.org because the current system requires that he do quite a bit of work every time that directories are moved or files are added. He proposed having a directory on the site which is a checked in version of the `docs/html` directory after a `make html`. He also suggested having docs for the latest release as well as for the 'svn head'. [perl #42293] t/doc/pod.t vs. tools/doc/pod_errors.pl <http://xrl.us/vrqh> In ticket [perl #42293] <http://xrl.us/vtqw>, Will Coleda suggested removing the script `tools/doc/pod_errors.pl` because the functionality is already replicated in `t/doc/pod.t`. Also, the script finds errors which the test does not, which requires investigation. Joshua Isom reported that he got a segmentation fault when he tried to run the script. When he persisted with running it, he found that it appeared to have a stricter POD checker. Jerry Gay thought that perhaps the script and the test were checking different files. Paul Cochrane found that on Gentoo the `t/codingstd/c_indent.t` test caused Perl to segfault, but with a new Perl compilation it worked. He was curious because he wondered if the error was due to Gentoo Perl. Joshua replied that he was using Darwin. Paul also remarked that the script reported where the errors were in the file, which the test didn't do. Jerry Gay and Nicholas Clark commented on this. [Fwd: YAPC::Europe Call for Hackathons] <http://xrl.us/vrqj> James E Keenan reposted a call for hackathons which was published for YAPC::Europe 2007. He felt that the Chicago Hackathon had been good for Parrot, and hoped that someone would lead a related Hackathon at Y::E. More information about the offer can be found on the Y::E website <http://xrl.us/vtqx>. Re: [perl #42299] AutoReply: $P symbolic register allocation bug <http://xrl.us/vrqk> Yehoshua Sapir remarked that the code in [perl #42299] <http://xrl.us/vtqy> worked on OS X. [perl #42300] [PATCH] t/pmc/sub.t: test for creation of lex by clone op <http://xrl.us/vrqm> Yehoshua Sapir submitted ticket [perl #42300] <http://xrl.us/vtqz> which contains a patch to test the creation of lex by the clone op. [perl #42305] [PATCH]: Configure.pl: Move STDOUT messages to Parrot::Configure::Messages <http://xrl.us/vrqo> James Keenan created ticket [perl #42305] <http://xrl.us/vtq2> to submit a patch which makes `lib/Parrot/Configure/Messages.pm` output messages to STDOUT (previously this was done by `Configure.pl`). This will make testing easier. It was applied as r18027. [svn:parrot-pdd] r17987 - in trunk: . docs/pdds docs/pdds/draft <http://xrl.us/vrqp> Allison Randal made a commit which moved PDD 15 (objects) out of the draft directory. Use of English pragma <http://xrl.us/vrqq> James E Keenan noted that `Configure.pl` uses one of the English variables, namely `$OUTPUT_AUTOFLUSH`. He wondered if there was a policy regarding the use of the named variables instead of their short versions. Jerry Gay felt that it was wrong to use the English variables. James said he would convert the variable while refactoring. He created ticket [perl #42333] <http://xrl.us/vtq3> to remind him of this task. Later this was done and applied as r18033. [svn ci] PMC documentation guidelines draft <http://xrl.us/vrqr> Jerry Gay remarked that he had committed a draft of PMC documentation guidelines in r17998. The document is meant to explain the style of documentation which should be used for core PMCs. Klaas-Jan Stol had some additions, borrowed from 'Perl Best Practices'. Joshua Isom questioned Klaas-Jan on some of the points, and Klaas-Jan elaborated. [perl #42312] src/pmc/os.pmc: bad use of stat(2) and lstat(2) <http://xrl.us/vrqs> In ticket [perl #42312] <http://xrl.us/vtq4>, the output of `t/pmc/os.t` which fails on Solaris 10 was attached. [perl #42313] improper casting to void * in src/dynext.c <http://xrl.us/vrqt> Ticket [perl #42313] <http://xrl.us/vtq5> contained a small patch to change `load_func` from a void pointer to NULL. Leopold Toetsch explained that the cast was being used. Nicholas Clark answered that the casting isn't allowed under strict ANSI C, but that he preferred assigning a plain 0 rather than a NULL. [perl #42320] [BUG] Memory leak with String pmc <http://xrl.us/vrqu> Mehmet Yavuz Selim Soyturk reported a memory leak in some example code. This was mentioned in ticket [perl #42320] <http://xrl.us/vtq6>. vtable cleanup and questions <http://xrl.us/vrqv> Jonathan Worthington reported that he is adding the new vtable entries required for PDD 15. He wanted to know if `become_parent` could be removed, or if it needed a standard deprecation cycle. He also noted that the subclass vtable method needed to be removed, but that it was in use by ParrotClass and ParrotObject. Jonathan also noticed `PMC* new_singleton()` and `PMC* get_anonymous_subclass()`, which don't appear to be used. He wondered if they should be removed. Finally, he wanted to know if `get_attr` and `set_attr` should be deprecated. Nicholas Clark confirmed that `become_parent` isn't used anywhere. Will Coleda voted for a standard deprecation cycle. Allison Randal confirmed this. She also agreed that the subclass vtable method won't be needed in the future, and that `get_attr` and `set_attr` could be deprecated when the full change to PDD 15 is complete. `new_singleton()` and `get_anonymous_subclass()` were described as "a case of being overly prepared for possible future needs." Minor notes/suggestions on PDD15 <http://xrl.us/vrqx> Klaas-Jan Stol had some suggestions for PDD 15. He had some suggestions for improving consistency. Additional comments were on opportunities for syntactic sugar and a proposal that operators such as `find_method` have the option of throwing an exception rather than returning a NULL PMC on failure. Allison Randal remarked that the exception question was under consideration in I/O as well, and that the consistency issue would be considered when she looked at the Opcodes PDD. Joshua Isom had a few suggestions as well. Acknowledgements This summary was prepared using Mail::Summary::Tools <http://xrl.us/qvno>, available on CPAN.

Darren Duncan wondered how one could declare an anonymous multidimensional array value which is compatible with the system Larry introduced. Larry explained that the semicolon notation is intended for slicing subscripts, which are two-dimensional, and it is therefore convenient to represent one dimension with a semicolon. There was further discussion on the syntax. [svn:perl6-synopsis] r14354 - doc/trunk/design/syn <http://xrl.us/vsas> A commit by Larry Wall made all punctuation potentially meta. Parrot Porters [perl #41837] [PATCH] integer overflow in include/parrot/sub.h <http://xrl.us/vdnz> Ticket [perl #41837] <http://xrl.us/vk9u> contained a patch which was required for 32-bit Solaris compilers. It was applied as r17853. [perl #42045] [PATCH] add return statement to clone in iterator.pmc <http://xrl.us/vrop> Ticket [perl #42045] <http://xrl.us/vtfx> includes a patch from Klaas-Jan Stol which adds a return statement which had been forgotten. The patch was applied as r17794. [perl #42082] [BUG]: Configure.pl: Misspecified option; 2 non-valid options documented <http://xrl.us/vroq> James Keenan explained that refactoring in `Configure.pl` had exposed two bugs in the file. He submitted a patch in ticket [perl #42082] <http://xrl.us/vtfy> which corrects the problems in the trunk. Joshua Isom had some questions about the supposed bugs; James explained why he considered them problems. Eventually the patch was applied as r17899. Syntax for Constructing new Objects (and classes?) <http://xrl.us/vror> This thread began with Klaas-Jan Stol asking about the syntax for constructing new objects because he thought that it was going to be changed. Allison Randal replied with examples of the two proposals for the new syntax. This led Alek Storm to ask if `new()` would be a vtable method or a PCCMETHOD. Jonathan Worthington confirmed that it is a PCCMETHOD. Allison elaborated that it is a class method. [perl #37997] r10604 build failure on Cygwin <http://xrl.us/vros> In ticket [perl #37997] <http://xrl.us/vtfz>, Ron Blaschke reported that `make test` fails on Cygwin for r10604, whereas r17772 builds without a problem. Joshua Gatcomb expressed his surprise, as he had not heard of anyone getting Parrot to work on Cygwin for several months. Eric Hanchrow offered to occasionally do a test build on his Cygwin system. Bernhard Schmalhofer suggested that Eric use the smoke system as documented in `docs/tests.pod`. Eric later reported that he could not get r17772 working. Paul Cochrane seconded Eric's report. Ron suggested using the absolute path for PATH, rather than just `blib/lib`. Eric got a bit further using this approach, but then he had another failure. Ron also noted that a few of the stm tests hang, which prevents smoking on Cygwin. chromatic asked if this was `t/pmc/stmlog.t`, but Ron thought it was `t/stm/queue.t` and `t/stm/runtime.t`. [perl #42110] [PATCH] Returning values from void functions <http://xrl.us/vrot> Steve Peters reported that a couple of functions are trying to return values from void functions. He included a patch in ticket [perl #42110] <http://xrl.us/vtf2>. Andrew Dougherty remarked that he had submitted the same patch the previous week, but not in RT. The patch was applied as r17793. Steve hoped there was a GCC warning flag which would catch this situation, but Nicholas Clark replied that he didn't think it was possible to look for this. He wondered if some other compilers could be coaxed into protesting. There was some discussion between Leopold Toetsch, Nicholas, Steve and chromatic over the value of `-ansi -pedantic`. [perl #42151] [PATCH] Assorted casting cleanups - part I <http://xrl.us/vrou> In ticket [perl #42151] <http://xrl.us/vtf4>, Steve Peters submitted a patch to clean up some casting instances. Kevin had a related request. Andy Dougherty also had a suggestion. Steve said that he intended to look at some of these ideas more closely as he worked on the project. chromatic and Leopold Toetsch also joined the thread. IRC discussion of smoking and branching <http://xrl.us/vrov> Allison Randal posted a discussion of the draft document 'Parallel development requirements,' which was announced in thread 'ParrotCode meeting this week <http://xrl.us/vsa6>'. There were some suggestions on how to improve the smoking system. For instance, Nicholas Clark noted that the Perl 5 system reports failures to perl5-porters, but the Parrot smoke failures aren't reported in a similar way. Another discussion involved commits which violate the coding standards. Many people contributed to this thread, and also to the IRC conversation which Allison posted. Re: [perl #42155] [PATCH] move members from Parrot_Interp to Parrot_Context <http://xrl.us/vrow> Alek Storm created ticket [perl #42155] <http://xrl.us/vtf5> to offer a patch which moved variables from `Parrot_Interp` to `Parrot_Context`. He noted that it broke some tests, and anyone who could figure out what the problem is will get a hug. Leopold Toetsch replied that it was deliberate that these variables were not in the Context structure. Alek replied that some of them already are in `Parrot_Context` and this patch simply moves the rest of them. Leopold and Alek had some further discussion on the matter. chromatic added his thoughts as well. Some benchmarking was done in an attempt to calculate the performance of Parrot before and after the patch. Joshua Isom also tested it. [perl #42156] [PATCH] Make invoke() return opcode_t* <http://xrl.us/vrox> Ticket [perl #42156] <http://xrl.us/vtf6> contained a patch by Steve Peters. This addressed some of the points raised in '[perl #42151] [PATCH] Assorted casting cleanups - part I <http://xrl.us/vrou>'. Paul Cochrane reported that the patch generated a warning for him. Steve made some additional changes to resolve the issue, and the new patch was applied as r17859. [perl #42161] [BUG] Parrot::Test throws "Can't spawn" warning on windows if a system call returns a negative value <http://xrl.us/vroz> Jerry Gay reported in ticket [perl #42161] <http://xrl.us/vtf7> that Parrot::Test throws a warning on Windows if a system call returns a negative value. He planned to commit a patch. [perl #42073] [BUG]: compilers/pirc/Makefile not cleaned up by 'make realclean' <http://xrl.us/vro2> James Keenan reported in ticket [perl #42073] <http://xrl.us/vtf8> that he expects `make realclean` to return his Parrot sandbox to its initial checkout status. He noted that this was not always happening. Klaas-Jan Stol was responsible for the file in question, but could not replicate the problem. James offered a patch and applied it as r17821. There were still some issues, which led James to ask if there were any Makefile experts who could help. [perl #42169] [CAGE] Create a sample subversion/config <http://xrl.us/vro3> Will Coleda created ticket [perl #42169] <http://xrl.us/vtf9> in response to a recent IRC discussion. Paul Cochrane offered a possible patch. Allison Randal pointed out that this was a global configuration which would affect all subversion repositories, not just Parrot. It was added to `editor/` in r17916. [perl #42170] [PATCH] Report line numbers on trailing_space.t <http://xrl.us/vro4> Will Coleda created ticket [perl #42170] <http://xrl.us/vtga> for a patch which was mentioned on IRC. He thought it was rather verbose, but didn't object to someone applying it. Jerry Gay and Eric Hanchrow offered comments. Paul Cochrane reported that the options had been added to `docs/project/cage_cleaners_guide.pod`. [perl #42215] [WEB]: Exporter PMC (and possibly others) missing from pmc docs page <http://xrl.us/vro5> In ticket [perl #42215] <http://xrl.us/vtgb>, Jerry Gay reported that the website parrotcode.org was missing some newly created PMCs. [perl #42218] [PATCH][Cygwin] Use bc on Cygwin <http://xrl.us/vro6> Ron Blaschke submitted a patch which enables bc on Cygwin if it is available. This was in ticket [perl #42218] <http://xrl.us/vtgc>. [perl #42074] [PATCH] add RECURSION_LIMIT macro <http://xrl.us/vro7> Ticket [perl #42074] <http://xrl.us/vtgd> contains a patch by Alek Storm which defines a `RECURSION_LIMIT` macro which had been hardcoded. It was applied in r17863. chromatic noted that it would be easy to make it a gettable/settable interpreter property and wondered if it would be of any use. Paul Cochrane replied that it already is that type of property, and that it would probably be valuable to be able to set the value at runtime. Leopold Toetsch reported that the interpreter already has it. Alek noted that the ParrotInterpreter PMC doesn't implement `set_pmc_keyed` and wondered if he could implement it. Allison Randal decided against it. There was a brief discussion on this. [svn:parrot-pdd] r17711 - trunk/docs/pdds/draft <http://xrl.us/vsau> Jonathan Worthington made a commit to PDD15 which added a proposal for role conflict resolution. [perl #42072] [BUG]: pmc2c.pl: Does anyone (know how to) use the 'no-body' option? <http://xrl.us/vsav> In ticket [perl #42072] <http://xrl.us/vtge>, James Keenan reported that he had experienced problems writing a test for the 'no-body' option in November/December, but hadn't gotten around to it. Because this option is not completely covered by the test suite, it is affecting other code. Therefore James is trying to figure out how it ought to work and had some questions about the warnings he saw. First Perl 6 Microgrant - Steve Peters on Parrot Portability <http://xrl.us/vsaz> Jesse Vincent announced that Steve Peters was the first recipient of the Perl 6 microgrant. Steve will be working on Parrot portability, and has already made several patches this week. More information about his proposal can be found in the grant application text. Details about the microgrant application procedure <http://xrl.us/vtgf> are available for those interested in submitting a proposal. A challenge... about Parrot <http://xrl.us/vsa2> Alberto SimÃµes mentioned a conference on languages, compilers and interpreters in Portugal. He thought it might be a good occasion to make a scientific publication about Parrot. Alberto felt that bringing Parrot to the attention of the scientific community would be a gain for both universities and Parrot. He offered to help with accommodation but not with writing the talk. Jonathan Worthington thought it was a good idea although he wouldn't be able to attend the conference. He noted that he had previously spoken to an academic audience and that it was challenging. He wanted to see the gap bridged, but noted that his own experience had involved some negative responses from a theory-oriented group. [perl #42105] memory leak in PCCMETHOD together with Parrot_runops_fromc <http://xrl.us/vsa3> Richard Hundt reported a memory leak, using ticket [perl #42105] <http://xrl.us/vtgg> to draw attention to it. [perl #42106] t/pmc/iterator.t t/src/io.t failed on Linux <http://xrl.us/vsa4> In ticket [perl #42106] <http://xrl.us/vtgh>, James Keenan reported some errors that he had encountered with `make test` on Linux. Eric Hanchrow replied that he thought it was his code, and that he was looking into the problem. [perl #42107] [PATCH] Intel C++ is not gcc <http://xrl.us/vsa5> Steve Peters submitted a patch to help identify GCC compilers correctly. It was attached to ticket [perl #42107] <http://xrl.us/vtgi> and applied as r17789. ParrotCode meeting this week <http://xrl.us/vsa6> Will Coleda wanted to discuss branching and the repository in general at the weekly Parrot meeting. Jerry Gay started a wiki page <http://xrl.us/vtgj> to keep track of ideas. [perl #42135] [PATCH] Fix overzealous flag removal in t/examples/shootout.t <http://xrl.us/vsa7> In ticket [perl #42135] <http://xrl.us/vtgk>, Andy Dougherty tried to address the problem of examples in `examples/shootout` specifying flags which aren't described anywhere. It was applied as r17792. Leopold Toetsch apologized for the lack of documentation and explained what the flags did. Testing PIRC <http://xrl.us/vsbc> Klaas-Jan Stol wanted to create a test suite for `compliers/pirc` but wanted suggestions on how he could do this. perl5-porters Working on punie + rindolf (the implementation) Reloaded <http://xrl.us/vro9> Shlomi Fish discussed the idea of writing a Perl 5 front-end which will compile Perl 5 code to Parrot. He wanted to name it 'rindolf' and wondered if Punie would be a good basis for the effort. He also wanted to know if he could have commit access to the repository. Allison Randal replied that it was an unusual approach and that she had doubts about the implementation plan, but that she would be interested in knowing what obstacles and successes came out of the effort. She thought that Punie would not be useful to Shlomi, given his plan. Her suggestion with regard to the repository was that he develop outside the tree and distribute it as a separate loadable module. Shlomi argued for being liberal with commit bits, and expressed his concern that the name Punie suggests that it is a toy. There was some continued discussion on the
