  Suggested patches

   Todd Rinaldo provided new patches in [37]Perl #127810 to remove . from
   @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.
