What about the possibility of making this hypothetic frame object an indexable, such that frame[0] is the current scope, frame[1] is the calling scope, etc.? On the same lines, what about closure[0] for the current frame, while closure[1] resolves to the closure the function was defined in? These would ensure that you could reliably access any namespace you would need, without nasty stack tricks and such, and would make working around some of the limitation of the closures, when you have such a need. One might even consider a resolve to be defined in any namespace, allowing all the namespace resolution rules to be overridden by code at any level.
