Since Emacs version 19 patchlevel 22 or so, there have been both a

Note that the perl-mode of emacs will have fits with C<"main'foo">
(single quote), and mess up the indentation and highlighting. You
are probably using C<"main::foo"> in new Perl code anyway, so this
shouldn't be an issue.

The Curses module from CPAN provides a dynamically loadable object
