Discussion

Karl Williamson suggests deprecating to_utf8_case. In short, not used in core, not used on CPAN, and the API is implementation-specific.

A simple trick mentioned in Perl #126841 for conditionally loading a module while suppressing import was explained. use if cannot suppress importing, but you can accomplish it in the following way:

BEGIN { require Module if CONDITION; }

Dave Mitchell asks if perl -V could list the build options one per line, since it's harder to read. The general opinion was that there is already plenty of output and it would be even longer to scroll.

Achim Gratz asks about differences between Linux and Cygwin when it comes to calling Cwd's abs_path on an nonexistent path.

Dmytro Zagashev asks about having subroutine signature aliases feature. Ricardo Signes noted that we would like to have this feature but no one is currently working on it.
