Suggested patches

Tom Hukins provided a patch in Perl #129229 to fix the parallel building.

Aristotle Pagaltzis provided a patch to document DirHandle as obsolete.

Nicolas (Atoomic) provided a patch in Perl #129235 Reduce SelectSaver memory footprint. to reduce memory footprint in SelectSaver by only loading Carp when it needs it.

Discussion

The topic of smart match 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 provided and important relationship to that part of the syntax in autodie. A discussion continued there, while another discussion continued around a suggestion by Father Chrysostomos.

Karl Williamson asked if there's a specific reason why there are no wrappers for strncmp. There are wrappers for strGT, strLE, etc.
