Many monks use GNU emacs or vi along with the Perl debugger, but ActiveState products are probably closer to what you are after. Some of their products are available free of charge, but you must see for yourself whether those are enough for you. You may find the ones that are only available for a fee affordable, too.

Why don't you post more of those problems here, by the way? Let the Monks Collective work for you.

You can use Super Search on this site or google for something like site:perlmonks.org IDE (and choose recent nodes) to come up with threads such as What's the best Perl IDE?, which probably has good pointers for you.

Hope this helps. Cheers.
