I just found the Lunar (Emacs) plugin for Eclipse.
It is a good supplement for Epic, as most Perl programmers are maybe used to emacs behavior
Lunar implements the Emacs automatic completion that I really liked in emacs (when I was still using it): Alt-/
Lunar could be helpful, especially since Epic does not complete variable names dynamically
There are some more editor enhancements in Lunar that can be used together with Epic
