Ok, but again we could argue over the definition of the word "needed". "Needed" by the program writer or "needed" by an implementation that keeps scopes around that are not accessible to the program writer anymore? EDIT: Ok, POST is a way to actually access such scopes, maybe even other introspection code, but the question is whether there is a need to create and keep these scopes at all when the writer does not indicate he wants them around?
I'm more than happy with renaming the problem to "goto creates spurious scopes". The question that I can't answer is whether "goto" does that for a good reason, like "goto is harmful, and has to do this to jump in and out of nearly arbitrary scopes", or that it really is a bug.
