Proposed patches
Tony Cook provides a patch for [28]Perl #125833 to disallow leading
colons
on require.
Tony also provided a patch for [29]Perl #127386 to clarify exit codes in
perl a bit more.
Bulk88 provides a patch for [30]Perl #126414 with a conservative
approach.
James E. Keenan provided a patch to revise an outdated portion of
perlmodlib to resolve [31]Perl #127435.
Discussion
On the matter of a script beginning with a colon, Abigail has [32]found
the behavior is indeed document, albeit in a possibly obscure place.
Karl Williamson [33]explains that the problem in [34]Perl #127392 (more
memory consumption in [35]constant) is not specific to [36]constant.
As he
[37]expands it is a Unicode-related loading that was changed from
run-time
to compile-time.
Karl hopes to tackle this in 5.24.
Tony Cook weighs in on [38]Perl #234128 saying it might not be worth the
effort.
