News and updates
Perl 5.25.1 is now available! You can read the release announcement
[1]here. The date for 5.26 is for May 2017. Those are typos. :)
Lexical subroutines are [2]no longer experimental!
Perl can now recognize version control conflict markers, thanks to a
patch
by Lukas Mai in [3]Perl #127993.
Karl Williamson created a META ticket for 5.24.1 blockers in [4]Perl
#128222.
Dave Mitchell provides his [5]grant report. In total, over 21 hours,
mostly spent on making [6]Scope::Upper work on latest versions of Perl
5.24.0.

Proposed patches
Klaus Baldermann provided a patch for perlbug in [37]Perl #128180 to add
more verbosity to the output, following a PerlMonks thread.
Michael Haubenwallner provided a [38]patch to avoid libperl.dll.a in
Cygwin.
Discussion
An update from H.Merijn Brand (Tux) that he had [39]finished preparing
builds for 5.24.0 for HP-UX ia64.
The [40]discussion around detecting perl6 in the shebang line continues.
Ed Avis [41]suggested to revisit a [42]suggestion by Kent Fredric to
bring
in [43]indirect into core. People have shown support for removing
indirect
object notation from examples in the core documentation, but have yet to
expressed a position about Kent's original suggestion. Sawyer X requested
that performance would be verified first, as well as a discussion
continues before making a decision on it.
Father Chrysostomos [44]pings us about the sub :const feature,
allowing to
make anonymous subroutines constants. Is anyone using it? Do you like it?
Does it have any problems? Should it stay experimental?
Father Chrysostomos [45]suggests perhaps only partially deprecating
[46]encoding.
There is an interesting conversation around [47]Perl #127531 (permit
\escape on right side of my). Father Chrysostomos made progress on the
topic, and several interesting comments on the topic by Ricardo
Signes and
Aristotle Pagaltzis.
H.Merijn Brand [48]updates that a machine which was used for smoking perl
core on HP-UX 10.20 had gone for good. Rest in piece.
Father Chrysostomos [49]suggests deprecating [50]encoding::warnings.
Glenn Golden [51]asks whether the usage of FileHandle.pm is applicable in
an example of [52]perlipc.
In [53]Perl #128227, Eric Wong suggests moving Perl to vfork for spawning
external processes. Leon Timmermans [54]found that originally Perl had
used it but abandoned it, while Ivan Pozdeev [55]adds that Configure asks
whether to use vfork and that the current POSIX standard (intended to
replace vfork) is posix_spawn.
Tom Wyant noted in [56]Perl #128213 that while literal left curly bracket
was deprecated in 5.22 and produces a compile error since 5.25.1, there
was no deprecation warning on 5.24. Karl Williamson [57]provides
extensive
comments on the change and its intent. This continued with a lively
discussion between Zefram and Yves Orton.
