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).

   Tony also provided a patch for [34]Perl #131894 (runtime error: shift
   exponent -2 is negative).

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.
