Well I saw coro, but "cloning the perl interpreter" sounds very expensive ... do you think this is a practical approach?

Theoratically speaking: If it's possible to safely do a 'goto &sub' without leaving the call frame, why shouldn't it be possible to simulater this state of the engine right after the call ... it's just a "return" without moving the process-pointer.

I'm not to fond about XS but maybe it would be possible to add this behaviour by intergrating special C Code manipulating the stack.

Saying this a have only a superficial knowledge of the interpreter, maybe someone can point to serious sideeffects which strictly disallow this approach.
