Discussion

   Yves Orton has [18]changed the sort order of the MANIFEST file.

   Yves Orton also [19]introduced his change of the return signature of
   scalar(%hash) to match 0+keys(%hash) as a continuation of [20]Perl
   #114576. In short, it didn't work the way you thought, and provided
   details that were not helpful for you to begin with. :)

   David Farrell [21]asked about a large amount of stat calls he was seeing
   from perl, and wondered if they were all necessary or whether it was
   possible to reduce them. Some options raised: Compiling Perl without .pmc
   support, and reducing the number of directories in @INC. Zefram notes the
   purpose of continuing to iterate through directories despite not
finding a
   module in them. Additionally with Linux detry caches, the actual stat
   calls would be faster than observed.

   However, at the end, Dave Mitchell [22]showed an indistinguishable
   difference for the stat calls between 2 @INC entries and 8.

   Unicode provides a Script_Extensions property (scx) which Karl Williamson
   [23]suggests using as the underlying for the single-value synonym in Perl
   (instead of the currently-used Script property, sc).

   Darren Duncan [24]asked if it were possible to release perl 5.24.1 with
   [25]List::Util 1.45, since it now carries a stable implementation of
uniq.
   This will likely not happen because maintenance releases should not
   include new features, and James E. Keenan [26]quotes the paragraph from
   perlpolicy.

   John Siracusa [27]reports some confusion around eval and $@, which seems
   to be a bug.

   Marc Lehmann has been banned from p5p for violating the Standards for
   Conduct.
