Except that it does. After calling locals() a second time, the result of the *first* call will be updated to reflect changes. It's not a frozen snapshot; you can't diff the two dictionaries to see what's changed (unless you use "a = dict(locals())" or something, which IS a snapshot). >From my reading of the description, you could also "assert a is b" - is that correct?
