Proposed patches

   Maxwell Hadyn provided a patch in [42]Perl #128105 to clarify the
   description of sprintf %.1g in perlfunc.

   Jim Cromie provided a patch in [43]Perl #128112 to improve the bug
   handling of glibc i-modulo.

   Chad Granum (Exordist) provided a patch in [44]Perl #128113 to upgrade
   [45]Test-Simple in perl blead.

   Lukas Mai provided a patch for [46]Perl #128131 to fix the link-time
   optimization (LTO) for GCC 6.

   Salvador Fandi=C3=B1o provided a [47]patch to fix a [48]PerlIO::encodi=
ng test.

   Tony Cook provided a patch in [49]Perl #126228.

   Karen Etheridge provided a patch in [50]Perl #128153 to upgrade
   [51]Module::Metadata to 1.000032 and another in [52]Perl #128160 to
   silence some diagnostic messages that were printed with the first patc=
h.
   Karen also submitted a patch in [53]Perl #128169 to remove internal te=
st
   modules from [54]Module::CoreList.

   Jerry D. Hedden provided patches to update [55]threads and
   [56]threads::shared to 2.08 and 1.52, respectively.

Discussion

   Mojca Miklavec has taken over maintainership of perl5 in MacPorts and
   [57]asks for advise on the appropriate configuration flags. An [58]ans=
wer
   provided by Craig A. Berry.

   James E. Keenan set up a smoke branch to test the upgrade patch in
   [59]Perl #128113 (mentioned above) and asks whether we should still me=
rge
   to blead for sensitive distributions. Tony Cook intends to apply the
patch
   soon. Tony [60]provided some benchmark results, and Chad Granum
   [61]provided an explanation of possible differences.

   The discussion about removing . from @INC is continuing, thanks to
   constant bumps from Todd Rinaldo. I recommend [62]reading about the to=
pic
   and its possible effects and various offered solutions.

   Ricardo Signes [63]asks if anything is preventing us from moving lexic=
al
   subroutines from "experimental". Father Chrysostomos mentions [64]Perl
   #123367.

   H. Merijn Brand (Tux) [65]reports he benchmarked Perl 5.24.0 and [66]s=
ees
   an improvement in speed.

   Timothy Madden [67]asked how to use I/O from native C extensions. Leon
   Timmermands [68]provides an answer.

   Karl Williamson [69]reminds everyone to update all RT tickets for 5.26
   pending release.

   Aaron Crane [70]asks about a proposal to deprecated and remove a
   C-specific function from [71]POSIX.pm.

   Following no objections, Dave Mitchell had [72]set -DPERL_PARENT_OP as
   default.

   Alberto Sim=C3=B5es [73]asks about the return keyword behavior in a ma=
p block.

   Note-worthy, Aaron Crane's [74]explanation for a particular bug.

   H. Merijn (Tux) Brand [75]had# a problem which Zefram pinned to a chec=
k
   done on the shebang for Perl 6 which created a false positive. There's=
 an
   active discussion on whether the check should be reverted or kept.

   Karl Williamson [76]asks about [77]Perl #57512 (implicit close()s are
   silently unchecked for error). Ricardo Signes explains the problem and
   Father Chrysostomos elaborates. It would seem that under the new conte=
xt
   stack Dave Mitchell has written, this class of errors could be fixed.

   Karl Williamson [78]simplified and generalized mathom.c, which is a fi=
le
   that keeps several definitions, originally meant for binary
compatibility.
   Dave Mitchell suggests cleaning up up after every stable release.
