News and highlights
Perl 5.25.5 [1]released by Stevan Little!
The epigraph reads:
We hypostatize information into objects. Rearrangement of objects is
change in the content of the information; the message has changed. This
is a language which we have lost the ability to read. We ourselves
are a
part of this language; changes in us are changes in the content of the
information. We ourselves are information-rich; information enters us,
is processed and is then projected outward once more, now in an altered
form. We are not aware that we are doing this, that in fact this is all
we are doing
-- Philip K. Dick, VALIS
Karl Williamson [2]updated that the Unicode 9.0 core specification is now
available in paperback form.
Jarkko Hietaniemi [3]provided an update about the -fsanitize=undefined in
gcc and clang.
[4]podlators 4.08 has been [5]released.

Suggested patches
Kevin Goess provided a patch in [38]Perl #129277: to rephrase a part in
perlrecharclass.
Pali provided a patch in [39]Perl #129298 to update documentation about
UTF-8.
Dan Collins provided a patch to fix the -i argument parsing raised in
[40]Perl #129336.
Discussion
Lukas Mai (mauke) [41]asked (Weird XXX comment in pp_ctl.c) about a
comment in the code from 1999.
Yves Orton [42]noted a problem in [43]List::Util not triggering magic.
Eric Brine [44]asked why COW (Copy On Write) is not used in a specific
piece of code. Explanation [45]provided (Re: Why isn't COW used here?) by
Dave Mitchell.
H. Merijn Brand (Tux) is [46]concerned about memory leaks in threaded
perls.
Hanno Böck [47]provided more context for [48]Perl #126599 (Unnecessary
preload wrapper in Makefile).
There were [49]additional [50]comments made in relation to [51]Perl
#123665 ('Useless use of a constant in void context' is compile-time but
not syntax warning), explaining the observed behavior.
Craig A. Berry [52]asked (Re: [perl #128972] Build failure on OS X 10.12
Sierra) whether [53]Time::HiRes uses the system clock_gettime() on OS X
10.12 Sierra. Does anyone have Sierra and can help verify what Craig is
asking?
Further [54]discussion on [55]Perl #126310 (no "Malformed UTF-8
character"
warning on single-quoted strings under use utf8) about whether a
malformed
UTF-8 error should die or not.
A discussion started from [56]Perl #129283 (Compile-time check for $1, $2
on RHS of s/// operator) on whether we should be catching situation in
regular expressions where a capture variable is used while there was no
capture there. The start of the read is [57]here (Re: [perl #129283]
Compile-time check for $1, $2 om RHS of s///operator) but the thread
continues further.
A. Sinan Unur [58]asked (I am confused about the future of Const::Fast)
about the future of [59]Const::Fast. The conversation continued [60]here.
In a conversation about parallel builds, it was [61]observed that
MANIFEST
is sorted as part of the build process and that can cause issues.
The discussion around a deprecation Pod document (tentatively referred to
as perldeprecated.pod [62]continues.
Michiel Beijen [63]raised an interesting problem when running Ubuntu on
Windows, which eventually ended up in opening [64]Perl #129348
([65]File::Find issue with link counts on Bash on Ubuntu on Windows).
Ævar Arnfjörð Bjarmason [66]provided a branch which removes the
ability to
call use UNIVERSAL;. Calling use UNIVERSAL qw(can isa) has been
deprecated
and warning since 5.12 and has been a fatal error since 5.22.
Dave Mitchell is working on cleaning up output to STDERR when building
perl. He [67]asked about a warning that appears when you build perl when
it exists in additional system directories. Should we still warn about
this? If so, should we still output this on STDERR or move it to STDOUT?
Andy Lester [68]started working on config.SH to clear up what
-Weverything
will include when using clang, since it doesn't map directly to gcc's
-Wall.
Dave Mitchell [69]provided a code review of a patch to bench.pl.
