Yeah, that's a large part of why I now think the given clause needs to be built on the same semantics that we already use internally for implicit out of order evaluation (i.e. decorators, comprehensions and generator expressions), such that it merely exposes the unifying mechanic underlying existing constructs rather than creating a completely new way of doing things.

I'm not sure what you mean by that. If you're talking about the implementation, all three of those use rather different underlying mechanics. What exactly do you see about these that unifies them? -- Greg
