It might be a bit misleading, because it doesn't actually correspond to a .yield (and thus I can envision CONTROL_YIELD as yet another exception type). I'm still brainstorming ways to get the gather/take semantics we need by using Parrot's .yield, but so far I haven't come up with a good way to do it. Pm
