Re^3: Continuations in Perl - Returning to an arbitrary level up the call stack

> Thanks! Return::MultiLevel is exactly what I was looking for.

Of course, it uses goto under the hood, just hidden behind massive abstraction and overhead ... 8-|

No, I understand that goto won't work with recursion like Return::MultiLevel. It's more like setjmp()/longjmp() and implemented using eval EXPR and goto.	[reply]

You are citing the POD, but I checked the source... Cheers Rolf ( addicted to the Perl Programming Language)	[reply]

I've checked the source. Such things cannot be implemented with goto. And setjmp()/longjmp() is best explanation found in pod. Implementation done using eval EXPR (EXPR is a string) + goto RANDOM_label. Each time you call sub recursively - label is different!	[reply]
