If I were you I'd check CPAN for related modules, maybe looking for "advice" (a LISP term) or "around" or "before/after"

> Any other wisdom to be shared here (bar the obvious "don't" and "use a cpan module")?

Well even if you do it yourself, you are free to look into the code

concerning:

1. You can check the target prototype before patching with prototype

3. It's possible to inspect the originating "home" package of a sub, again try searching the archives here°

Nota bene: Perl has a trace option ( perlrun ) and the debugger has many means to "watch" subs ( perldebug )
