:) Hmm. The trouble here is that a 'for' loop is basically doing assignment. When you say "for x, h(x) as y in things", what Python does is (simplified): _it = iter(things) while not StopIteration: x, (h(x) as y) = next(_it) ... loop body ... So what you're asking for is something that doesn't behave like an assignment target, but just does its own assignment. Bear in mind, too, that "x = next(_it)" is very different from "x, = next(_it)"; which one is "x, (h(x) as y) = next(_it)" more like?
