Suggested Patches

   Tony also provided a patch for [12]Perl #131725 (number parsing).

   Tony Cook also provided a patch for [13]Perl #131786 (Linker error with
   pp.o if -mieee-fp is in CFLAGS. "multiple definition of \_LIB\_VERSION").

Discussion

   Dave Mitchell [14]asks what sv_utf8_upgrade() should do if it receives a
   qr. It was decided to simply make it a NOOP.

   [15]Perl #68534: (Enhancement: which expression (not just scalar) was
   uninitialized in eq) was upvoted and there's a [16]discussion on the
   feasibility of providing additional situations in the uninitialized
values
   warnings.
