Five minutes in The New And Improved PM Super Search turned up the following threads:

• Your editor of choice is..
• perl perl use with VIM editor
• Perl Development Environments
• Visual Perl & ActiveState
• Pretty Win9x Perl Editor/IDE?
• Editor/IDE Reviews.

You may also wanna venture over to ActiveState to check out their preview release of Komodo, an IDE for Perl, Python, and JavaScript.

tilly already mentioned above that neophyte has a pretty comprehensive list o' editors at her home node, so I won't repeat it here.   That you should check out neophyte's node, that is.   ;^)
