Re^4: subclass discovery at runtime

Are you doing it in that order? Because the @ISA = qw(SuperClass); only happens at runtime, and by the time the print executes you haven't yet arrived at it. Wrap it in BEGIN {} and it will work.

Makeshifts last the longest.

Yep... You're right... I just figured that out... Discovered an issue with recursing thru the namespace too; seems there's a 'main::main::' entry, which causes infinite recursion, so you'd need to keep track of what namespaces you've checked...	[reply]

Sort of. There's a `main::` in every package; just skip that entry and you'll be fine. Makeshifts last the longest.	[reply]

Right... Makes sense actually... That way every package can easily access the main package... Ah well... My duplicate-checking code seems to work too... At least I've learnt a bit about the symbol table and such because of this thread... :)	[reply]
