If you want C-like infinitely nested scopes, you basically have to
have declared variables, which Python doesn't want. There are other
languages which are very Python-like but do have declared variables
and infinitely-nested scopes, but I'm not sure I want to deal with
this kind of anger on another mailing list, so I won't name one. Once
again, though, you need to (a) learn the language before getting
irate, and (b) play to its strengths, not its weaknesses. Python's
requirement to declare all globals is a major weakness when you have
hundreds of globals, so don't do that (or don't complain about how
your code looks when you do).
