I agree that it'd be cleaner making the frame locals a dict-like object with write access, but I wouldn't be able to do that because of time constraints (and I'd have to research more how to do it and it'd be much more intrusive I guess).

So, if it's guaranteed that it'll be accepted I can provide a patch (changing the clear to 1) of the savelocals() version.

I guess I don't agree this falls in the language moratorium, but if that's the case I can wait 1 or 2 more years before submitting the patch :)
