Happy holidays!
News and Updates
Perl 5.27.7 is [1]released!
The new smart match broke a considerable amount of CPAN modules and will
therefore be reverted.
Andreas Koenig [2]provided a patch to update [3]CPAN.pm to 2.20-TRIAL.
Dave Mitchell [4]suggested making PERL_OP_PARENT compulsory in 5.28.0.
This has since been done.
Karl Williamson [5]provided a new version of his implementation of script
runs.
Is it time to declare string- and number-specific bitwise ops fully
stable
and enable it in use v5.28? Check [6]Perl #123707.
Pip Cet [7]provided an explanation of how he uses the SpiderMonkey GC to
find memory leaks in Perl.
[8]podlators 4.10 is [9]out.

Suggested Patches
Marco Fontani provided another patch (which was merged) to resolve
[149]Perl #116080 (Doc issues for system, exec, qx).
Karl Williamson [150]wonders (regrepeat()) whether we should introduce an
optimization for repeating characters on a pattern like (foo)+.
Discussions
Leon [151]raised the need for a language design process.
Zefram [152]raised (smartmatch/switch deprecation for 5.28) the topic of
smart match again with regards to what to deprecate in smart match.
Karl Williamson [153]suggested two deprecations: literal \v in patterns
except under /x and /[#]/xx.
