Suggested Patches
Tony Cook provided a patch for [31]Perl #131836 (use-after-free in
Perl_yylex).
Tony also provided a patch for [32]Perl #131746 (runtime error: null
pointer passed as argument 1, which is declared to never be null).
Another patch by Tony to [33]Perl #131893 (runtime error: signed integer
overflow).

Discussion
Following [35]Perl #131725 (number parsing), Tony Cook suggested
deprecating a e-number without a number after the 'e' character, because
fixing it breaks some of CPAN.
Zefram is [36]discussing the my_strerror() function and $!.
Abigail [37]continues investigating the behavior of @{^CAPTURE} and now
with (?(DEFINE)).
Herbert Breunung [38]started discussing ideas for changes in perldoc.
