|P is for Practical|
I agree that Komodo is a very nice editor, especially if one is just learning. However, I've had equally good results with the Open-Source Eclipse project, using the incredible EPIC plugin to enable Perl projects.
It takes a little more initial setup than Komodo, but I have found many more useful features in Eclipse/EPIC as I have been writing more and more code; Eclipse also seems to perform better for me, but YMMV on that one.
I will say this: I really enjoy ActiveState's graphical debugger, part of their "PDK" software. Unfortunately, I don't think that component is available for free. A close second is Devel::ptkdb, which is a Tk-based GUI debugger for Perl code.
