maybe this doesn't work for you. I have a program which collects data from another computer and then works with that, interactively.

Collecting the data takes 3-4 minutes, which makes debugging quite slow. To speed it up, I can now load Perl code from a file interactively into my Perl script and then run that (via eval()). If I make a mistake, I edit the code in the file and re-load it into my Perl script again. Later, when I know it works, I make that code permanent.

I don't use a debugger, only print() and staring at the code.

Maybe you can use this trick.

Good luck,
Alex.
