The "old wisdom" on comp/lang.perl.misc, when new people asked what was the best IDE to Perl programming, was "Unix".

You get both editors to choose from, vi _and_ emacs! All the man pages you could possibly want _and_ perldocs! Of _course_ as a Perl newbie you'll be able to fall back on gdb for complicated debugging where print statements no longer cut it.

I have a whole other screen for my terminal(s). The IDE already has enough going on in it.

why wouldn't you want the diffs in the IDE? Its richer and you can do more with them
