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

in reply to Continuations in Perl - Returning to an arbitrary level up the call stack

There's Scope::Upper which provides unwind_at that essentially allows you to perform a return higher up the stack.

You could also try Return::MultiLevel which seems to provide a pretty sane interface for continuations, albeit requiring some co-operation between caller and callee. Also take a look at some of MAUKE's other modules that follow on from that.

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-|
