News and updates

   If you like [1]Coro, and you are wondering about the support for
perl, you
   can view the [2]following patches by Dave Mitchell (mentioned below as
   well) that allow Coro to work correctly on perl. Whether they will be
   applied in Coro is a different question.

   Karl Williamson [3]updates that Unicode 9.0 Emoji is now available for
   adoption.

   Ivan Pozdeev's patch on removing superfluous -Ilib was [28]merged.

   Salvador Fandino's patch to fix a test of [29]PerlIO::encoding was
   [30]merged.

   While Dave Mitchell [31]fixed one warning produced by GCC 6.1, there is a
   disagreement on another (with an explanation) and comments on others.

Proposed patches

   Jim Cromie [32]provides revised patches for [33]Perl #127885 (enhance
   bench.pl to test same perl under different options/args).

   Dan Collins provided patches to test the problem presented in [34]Perl
   #128420 (changes in regex recursion in 5.25).

   Dave Mitchell [35]provided revised patches for [36]Coro which can be
   merged to restore the compatibility with perl.

Discussion

   Dave Mitchell [37]comments how [38]Perl #127774 (Segfault in
caller()) was
   properly fixed as part of the context stack system rework, which - if
   you're interested in the context stack - you might find interesting as
   well.

   Dave Mitchell [39]updates that, based on the responses in the thread
   discussing listing build options in perl -V, he made a change to list
each
   option per line.

   On the topic of inconsistencies in memory size types in the code, Dave
   Mitchell [40]notes his preference on standardizing Size_t and SSize_t.
   Father Chrysostomos adds that he prefers STRLEN and MEM_SIZE because he
   views them as clearer. To continue this, Dagfinn Ilmari Mannsåker had
   [41]posted a branch that standardizes some of this. All STRLEN and
   MEM_SIZE had been converted to Size_t and converts ssize_t to SSize_t.

   Aristotle Pagaltzis [42]provides a good break-down on the comments
made in
   [43]Perl #127684 (operators ||| and &&&) and suggests the ticket be
   closed.

   Dave Mitchell provides comments on [44]Perl #128083 (silent encoding of
   filenames with UTF8 flag set) and how system works.

   Tony Cook provides additional [45]comments on [46]Perl #127663
(safety for
   -i option).

   Andreas Koenig [47]reports some verbose test results due to the new
   unescaped literal left-brace warning. Karl Williamson delved into the
   presented cases and provided a pull request to the respected author.

   Dave Mitchell reverted the commit that updates [48]Time::HiRes to 1.9735
   because it causes tests to hang, until the issue is resolved.

   In relation to [49]Perl #128226 (remove the requirement for null
   termination on PVs), Dave Mitchell had done a survey of SvPV* in the perl
   source and of SvPV_* and SvPVX*.
