I really like the idea if a script that guides you through using the perl debugger. Like some of the other monks I tend to fall back on print statements and Data::Dumper; which I know is daft but I am really lacking in skills in the debugger.
I like the idea of a script that basically tells me to try various things and explains why. So when you try and run it direct it tells me to run it with -d. Then there are perhaps comments/prints that tell me what to do. That describe perhaps a problem and a command that helps me identify the problem etc.
Happy to act as a guinea pig on this. :-)
