Perl 6 Summary for 2004-01-03 through 2004-01-11
    Welcome to another Perl 6 summary. In this summary, we will explore such
    thrilling issues as multi-dimensional slices of Chinese food. After all,
    the amount of sauce any piece of Chinese food can absorb is proportional
    to its surface area, which is a direct function of the number of
    dimensions in which it is sliced (provided that we ignore degenerate
    cases like fractal cuts of Peking duck).

  Perl 6 Language
   1x6 vs 6
    Craig DeForest wondered how to disambiguate a 1x6 2D array slice from a
    6 element 1D array slice. He suggested a syntax inspired by PDL. Larry
    admitted to not having examined this particular issue and stated that he
    was open to suggestions. Some suggestions arrived.

   code as comment
    St├ęphane Payrard wanted to know if there is an easy way to alias
    arguments to a function. Thus allowing a longer version for readability
    when calling the function and a short version inside the function. Larry
    suggested "$s is named<subject>", which I like. The thread then devolved
    into punning in French.

    <http://xrl.us/eouv> -- initial post on p6c

  Perl 6 Compiler
   Pascal -> Pcode -> Parrot -> Profit
    Sven Schubert asked about the feasibility of putting Pascal on Parrot.
    He noted that with the infrastructure mentioned in "Perl 6 and Parrot
    Essentials" the problem would not be too bad. Apparently "Essentials"
    makes a few promises that we have yet to live up to. But we are working
    towards it. In the mean time, St├ęphane Payrard suggested a way for him
    to kill to bird with one stone: Pcode.

    <http://xrl.us/eoux> -- initial post

   Grammar improvements
    Luke Blanshard submitted some rules for Perl6::Grammar. Luke Palmer
    committed a slight variantion of his work, and the hacking commences...

  Parrot
   pop_pad
    Peter Christopher wondered why pop_pad had not been implemented last
    week. This week Leo implemented it and asked for tests.

    <http://xrl.us/eouz>

   Resizable arrays
    Simon Glover asked why ResizablePMCArray was so different from all of it
    Resizable*Array bretheren. The answer is the Leo improved it. This
    brings up an obvious task for someone looking for a reasonably friendly
    chunk of Parrot to work on. Rationalizing the implementation of the
    various Resizable*Arrays would probably be a good task for a novice
    looking to dig into something. Perhaps one who is on winter break...

    <http://xrl.us/eou2>

   Parrot 0.1.1 nci troubles
    Ian Joyce noticed that parrot 0.1.1 was having some trouble with nci.t.
    Leo admitted that this was the case, but it is fixed in CVS.

    <http://xrl.us/eou3>

   test or benchmark
    Nicholas Clark wondered if resizablestringarray.t was actually a
    benchmark, because it had a big number which was really hurting his poor
    machine. Simon Glover admitted to the copy paste error.

    <http://xrl.us/eou4>

   x86 solaris 2.5.1 and 2.7
    Andy Bach and Nicholas Clark worked towards getting parrot happier on
    the aforementioned architecture. This thread seemed to peter out when
    Nicholas asked "how do we run a callback unconditionally after
    gccversion is known, independent of its value?".

    <http://xrl.us/eou5>

   VTABLE_call_method
    Leo and Sam had a disagreement about whether a call_method vtable would
    make sense. I think that we are waiting for higher intervention...

    <http://xrl.us/eou6>

   updated perlhist.txt
    Will Coleda applied Bernhard's patch updating perlhist.txt and
    streams.t.

    <http://xrl.us/eou7>

   Warnock Warnocked
    Will Coleda applied the long Warnocked update to Warnock's contact
    information with only a trace of irony.

    <http://xrl.us/eou8>

   gcov of perlarray.pmc reaches 100%
    Simon Glover got perlarray.pmc to have full test coverage. Nifty. Some
    brave soul (possibly fitting an earlier description) should try this
    with the Fixed*Arrays...

    <http://xrl.us/eou9>

   Parrot under Solaris 9
    Nicholas Clark, Andy Doughery, and Christian Aperghis-Tramoni all tried
    to convince Parrot to work on Solaris. They are brave souls.

    <http://xrl.us/eova>

   parrot-config updates
    Peter Christopher asked questions about the parrot-config.imc. He also
    provided an initial solution.

    <http://xrl.us/eovb> -- questions

    <http://xrl.us/eovc> -- solutions

   Key Question
    Simon Glover noticed some bad behavior with respect to Key PMCs. Leo and
    Sam both admitted that it was bad and that some work needed to be done.

    <http://xrl.us/eovd>

   Parrot PDL
    Bernhard Schmalhofer posted a pointer to PDL. Luke Palmer pondered
    Piddles as Parrot PMCs. Craig DeForest proposed a path passing through
    PDL's PP and pausing at Parrot. (Parenthetically, perhaps the
    preponderance of Ps in Perl, Parrot, and Python should push me to
    alliterate with another available letter.)

    <http://xrl.us/eove>

   Parrot Syntax Engine
    Henrik Gulbrandsen introduced the powerful Parrot Syntax Engine. Leo
    asked a few questions to which Henrik provided answers. All in all, it
    looks really cool and makes me a little jealous that I did not develop
    the Tomita algorithm first.

    <http://xrl.us/eovf>

   s/libnci.so/libnci_test.so/g
    Bernhard Schmalhofer moved libnci.so to libnci_test.so, as it really is
    for testing. Leo applied it.

    <http://xrl.us/eovg>

   segfaulting readline
    Matt Diephouse managed to segfault Parrot using readline. Leo fixed it.
    Matt pointed out a new bug that it introduced.

    <http://xrl.us/eovh>

   substrings of invalid ranges
    Matt Diephouse noticed that taking a substring of an invalid range had
    odd results. Simor Glover provided a bunch of tests for it. Leo applied
    the patch, but mentioned that these corner cases needed to be hammered
    out authoritatively.
