Rejected issues
Suggested patches
Karl Williamson [34]provided a patch for [35]Perl #130010
(v5.25.5-184-ga5540cf breaks texinfo).
Todd Rinaldo provided a patch in [36]Perl #130087 to reduce module
dependencies of [37]B and [38]O.
Nicholas R. (Atoomic) provided a patch in [39]Perl #130084 to reduce
memory consumption for hashes at the (hopefully low enough) cost of
speed.
Nicholas also provided a merged patch in [40]Perl #130082: to clean up
PERL_VERSION checks in .c files.
Nick Koston provided a patch in [41]Perl #130101 to reduce the memory
consumption of [42]Data::Dumper.
Andy Lester continues his work and provided a patch with various
tweaks to
time64.c in [43]Perl #130121.
Discussion
Following Nicholas' patch in [44]Perl #130084, Yves Orton and Nicholas
[45]discussed the issue.
Todd Rinaldo [46]suggested deprecating a newly added option
(PERL_USE_UNSAFE_INC) in 5.30, in order to not normalize its usage and
keep it for the transition period to having no dot in @INC.
Dave Mitchell [47]noticed that lexical subroutines can override keywords.
Father Chrysostomos [48]explained why it is intentional.
Yves Orton [49]provided an explanation of ties and magic (variables @+,
%+, and %-) and saving state.
