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.
