I have some extensions. This is straight out of my .gvimrc, so it has the menu extensions. beware.

:46amenu Perl.Set\ Perl\ Make :set makeprg=perl\ -c\ %
:!perl -c %rl.Build\ \ \ \ \ \ \ \ \ \ \ \ <F5> :w
:!perl -d %rl.Debug :w
:46amenu Perl.Run\ \ \ \ \ \ \ \ \ \ \ \ \ \ <F6> :w^M:!perl %

The % refers to the current filename. Incidently, when Tim Vroom, the maintainer of this here site, and I worked together, we had a full integrated BackOrifice messaging system. I ran linux, and because he is a tool of the man, he ran windows.
Gvim is the greatest thing since sliced bread.
