Re: Re-vitalizing cperl-mode

As well as `perl-mode`, indeed.

Indeed, neither `perl-mode` nor `cperl-mode` are getting much love
these days.

Much better would be for you to step up as maintainer of the package:
it's likely that in many cases the "Emacs dev team" wouldn't really have
the resources or expertise to judge such changes.

We can give guidance and feedback on the quality of the Elisp code, of
course.

Yes, we could easily distribute emacs.git's ` cperl-mode.el` as a GNU
ELPA package as well (like we already do for python.el and a bunch of
others).

Since `cperl-mode.el` is distributed with Emacs, its better to try and
obey the conventions used for Emacs's own Elisp code.

Adding test cases under emacs.git/test would be a great contribution
as well (there's currently a very limited set of testcases in
test/manual/indent/perl.perl).

The main rule there is that code's copyright needs to be assigned to
the FSF.  I'll contact you off-list for that.
