@INC.
Peter Rabbitson (ribasushi) wrote an alternative patch for [38]base.pm.
Kent Fredric [39]sent it to the list. The releases of 5.23.3 and 5.24.1
will be delayed until this patch is discussed and decided on.
Dave Mitchell provided a new patch for adding travis.yml file in [40]Perl
#123981.
Tony Cook provided a patch for fixing [41]Perl #128263 (Assert fail in
Perl_magic_get without other symptoms).
Leon Timmermans provided a patch for [42]Perl #128902 (MakeMaker
02-xsdynamic.t failure in AIX 5.3 with blead be93048a) [43]here.
Smylers provided a merged patch in [44]Perl #128910 to remove state (@a)
upcoming feature claim from perldiag.
Bulk88 provided a merged patch in [45]Perl #128929 to silence MSVC
warnings for NATIVE_UTF8_TO_I8/I8_TO_NATIVE_UTF8.
Tony Cook provided a patched for [46]Perl #128095: (Failed test
dist/IO/t/cachepropagate-unix on OS X with Perl 5.22, regression from
5.20).
Bulk88 provided a patch to automatically detect GCC vs VC and set VC
version number on Win32 in [47]Perl #128930.
Discussion
Jarkko Hietaniemi [48]asked if make_ext.pl script is required every
single
time make perl is run. It's costly. Craig A. Berry [49]provided some
history and Nicholas Clark (who introduced this change [50]chimed in with
further explanations.
The [51]discussion (Internals:: undocumented) around documenting internal
functions continued. It resulted in Yves Orton [52]committing changes to
both move some functions and document them.
Father Chrysostomos [53]noticed that [54]Encode uses C++ comments instead
of C comments. Perl uses C89 and guarantees support for compilers that do
not understand // comments.
A [55]suggestion on how to print Size_t and SSize_t by John P. Linderman,
along with a fun anecdote about Awk, ANSI, and floats.
Michael Schroeder pinged the topic of a suggested change to [56]base.pm.
Father Chrysostomos [57]responded with the possible problems this
suggested change has.
On a fascinating [58]thread (Flailing randomly at ops), Paul Evans
(LeoNerd) asked for help understanding munging the optree to reach a
particular goal he has. Father Chrysostomos [59]provided insightful
comments, and Paul is [60]writing about it on his blog.
