EPIC is a pretty cool project I came across today. Its aim is to provide a set of Perl oriented plugins (editor, debugger, regex editor) for the Eclipse open source IDE originally developed by IBM and now supported by a large community as well as many companies. This may eventually provide an alternative to ActiveState's Komodo IDE.
I'm not much of a GUI or IDE person, but if anyone else who prefers that sort of tool wants to give it a whirl, that would be cool.
Makeshifts last the longest.
