Corrections
The previous summary mentioned [1]Perl #125833 as a problem with leading
semicolons. That was a typo. It's leading colons. Thank you, Tony Cook,
for the correction!
News and updates
Perl 5.23.8 is now available! You can read the release announcement
[2]here.
Tony Cook provided another grant [3]report filled with interesting
details
about his work. Around 18.5 hours spent in which approximately 14 tickets
were reviewed or worked on, and 5 patches were applied.
Additional following grants reports of Tony available [4]here and
[5]here.
They show in total about 40 hours of work, during which approximately 21
tickets were reviewed or worked on, and 5 patches were applied.
Dave Mitchell provides his grant [6]reports. In total, over 14 hours of
work, focusing mainly on an issue with Solaris failing to link when using
a combination of -Dusedtrace and -Duseshrplib.

Proposed patches
John Peacock [57]submitted a patch to update [58]version.pm with the
version which was released to CPAN.
Bulk88 provided a patch to try and fix [59]Perl #125296.
Bulk88 also provided a patch in [60]Perl #127588 to silence a warning in
Win32CORE.
Following another ticket relating to memory consumption in regexps
([61]Perl #127568, which was consolidated with [62]Perl #127392), Karl
Williamson provided a set of patches to reduce the memory consumption for
non-ASCII regexps. The patches seem promising from Atoomic and Todd
Rinaldo's reports.
Bulk88 provided a patch in [63]Perl #127636 to "teach" makedef.pl an
alternative macro to PERL_COPY_ON_WRITE.
On a related topic, Bulk88 provided a patch in [64]Perl #127635 trying to
fix s///r with -DPERL_NO_COW attempting to modify the source SV. Tony
Cook
made suggested alterations.
Vadim Konovalov [65]submitted a patch to modernize [66]strict.pm. It was
discussed heavily, including problems it introduces.
Discussion
Dave Mitchell makes another [67]attempt to work out the semantics of @_
for a subroutine with signatures. I recommend reading it and providing
input!
Ed Avis suggests making perl either warn or error when using or defining
variables with special names, such as @$, since they are most likely a
typo. Abigail [68]provided interesting input on the effects of this.
Steve Hay [69]raised an old topic relating Winsock errors. He proposed to
put Winsock error codes into $^E after each Winsock function call, export
the WSAE-related error constants from [70]Errno.pm and [71]POSIX.pm for
checking these error codes against, instead of $!, on Windows from 4.24.0
onward.
On the topic of 5.24 blockers, the context stack revamp has also broken
[72]Algorithm::Permute but it is yet unclear if this is worth fixing.
More
importantly, however, is that [73]Devel::NYTProf is also broken. Dave
Mitchell was able to [74]mitigate one problem but more involved work is
required to get it to fully pass.
Jarkko Hietaniemi provides an update for [75]Perl #122482 (introducing
netlib dtoa.c library to convert between decimal and binary).
The conversation around stringifying a double (relating to [76]Perl
#122482) [77]continues.
Dave Mitchell has been looking into various [78]warnings that come up
during the blead build run. These come from several .pm files not
containing any POD documentation.
Bulk88 [79]provides [80]more information on [81]Perl #125296.
