Suggested patches
James E. Keenan provided a patch in [28]Perl #128856 (DirHandle: Improve
test coverage and provide descriptions).
Father Chrysostomos provided a patch for [29]Perl #129224 (Bleadperl
breaks [30]Data::Swap), which Andreas J. Koenig reports works.
Tom Hukins provided a patch in [31]Perl #129229 to fix the parallel
building.
Aristotle Pagaltzis [32]provided a patch to document [33]DirHandle as
obsolete.
Nicolas (Atoomic) provided a patch in [34]Perl #129235 Reduce SelectSaver
memory footprint. to reduce memory footprint in [35]SelectSaver by only
loading [36]Carp when it needs it.
Discussion
The topic of smart match [37]came up (pounding the smartmatch drum)
again,
as Ricardo Signes (rjbs) asks whether we should fix it, kill it, or just
not recommend anyone use it. The proposed fix for it is to reduce its
scope significantly. Tony Cook provided a patch which does this, but
supports overloading on both sides. There are suggestions to remove the
LHS (left hand side) overloading in order to reduce its confusing bits
further. Aristotle Pagaltzis [38]provided and important relationship to
that part of the syntax in [39]autodie. A discussion continued there,
while another discussion continued around a [40]suggestion by Father
Chrysostomos.
Karl Williamson [41]asked if there's a specific reason why there are no
wrappers for strncmp. There are wrappers for strGT, strLE, etc.
