If you need to know which return returned, you might be able to wrap return using Keyword::Declare or Filter::Simple.

Be warned: These are very powerful, therefore dangerous to use.

I'd recommend Keyword::Simple , but for completeness: a sub can be left without return. Possibilities include: implicit return at body's end goto label in caller chain goto &sub die exception Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply]

This is true, of course. So, would still need something like End to catch those cases. (Though the implicit return at the body's end could be "hand modified".)	[reply]
