Correct.

Anecdote time: a colleague asked me for help with a recursive call that 
wasn't behaving as expected. He showed me the code, and I couldn't see 
anything particularly wrong with it, except that there was one 
identifier for which I couldn't see a definition. I asked him about it, 
and he said it was at the top (i.e. at file scope). When I'd finished 
slapping him about the head, I asked him why he'd done that, and he said 
that he'd just put it there while he got the code working. I moved the 
definition into the recursive function, and bingo! Everything worked fine.

RULE ONE: DO NOT USE FILE SCOPE OBJECTS!

RULE TWO (for experts only): DO NOT USE FILE SCOPE OBJECTS YET!
