Ok, how about this x = 'a' for x in range(10): foo(x) bar(x) What value do you expect 'x' to be in bar(x)? Because it sounds like you were expecting it to be bar('a') instead of bar(9). Hrmm, I just remembered. That's a C thing, isn't it? The loop variable being only defined inside the loop. God that makes to happy. Forgetting stuff like that. Maybe in another 20 years I'll forget everything I ever knew about static typed languages and pass into hacker Nirvana. ><{{{*>
