As one who is new to Perl, I have yet to figure out just what is a necessary tool. I'm finding out that I really don't need everything I've been using.
I was using kdevelop, which is a handy way to keep stuff in projects. I found out by accident that all I really need is kate, which allows me to edit, and then pop down to use the terminal emulator for running the program. Sweet.
Perl just doesn't need anything fancy. I don't need an IDE. Every day, Perl gives me some new surprise - making it much easier for me to get something written quickly. Kind of makes me feel like a kid at Christmas time.
