in reply to 'extract' subs from source code

This is just an idea - not a real solution - but hopefully, more knowledgeable monks can either comment on it's viability, or explain it's unsuitability:

Since sub names are in the "main" namespace, how about using the perl debugger to load and print the sub info, without actually executing the program ?

    They probably are, but they might not be.

    ... without actually executing the program?

    use or BEGIN or other metaprogramming mechanisms may modify what's available. You'll probably be fine with most scripts, but that's no guarantee.
