Re:x3 Double your return!!!!

I wasn't seriously suggesting this as useful code.

I intended the question more as a perl puzzle that I couldn't solve. The code was only to illustrate the question and the critical text was is it possible?

Reading the responses and re-reading my initial post I obviously didn't make my intention clear enough.

Sometimes though, a joke or japh ends up being useful.

I don't think Quantum::Superpositions was intended seriously yet junctions (or whatever the name is now) is going to be in perl6.

Not possible in perl5 AFAIK.

Since parrot is supposed to support continuations something like this might be possible in perl6 I guess.

I know of one language that supports the idiom. Pop-11 has chainfrom, chainto, exitto and exitfrom which cover the full gamut of exit variations. However, apart from using chainto to optimise tail recursion I've never used them in "real" code :-)
