I use mcedit, the internal editor of Midnight Commander. It's advantages are:

it is simple to use

very nice colored syntax highlighting for Perl scripts,

to run your script after an edit, you just hit enter on the file in the nice 2 panel file-list display.

has the file management power of mc, just an escape away, like copy,rename, move, chown, chmod, search/replace,etc.

Of course, Midnight Commander sucks on Windows, so it's really Linux only.
