documentation
   regarding the nature of $a and $b in sort().

S_invlist_is_iterating and
       S_invlist_max be const.
     * [33]Perl #130592: [PATCH] Add prototypes for 6 mathoms to satisfy
       -Wmissing-prototypes.
     * [34]Perl #130596: Perl_utf8_to_uvchr_buf has no prototype in any .h
       file.

Discussion

   Dave Mitchell [35]asked several questions about the slowness of two
tests:
   ext/XS-APItest/t/handy.t and ext/XS-APItest/t/utf8.t.

   Todd Rinaldo sent an email to cpan-workers regarding the toolchain and
   removal of . from @INC. [36]Discussion continued.

   Dave Mitchell has [37]made the desired changes to the output format of
   op_dump() discussed previously.

   Karl Williamson [38]notes that perl still attempts to compile regular
   expressions, even if there are parsing errors, and wonders if there's a
   valid reason for it.
