You've fallen into a common terminology trap: we talk about that keyword as "declaring a global" or "declaring as global", when that keyword's purpose would be better described as "declaring that when making reference to the following variable(s), I mean the one(s) in the global namespace rather than this function's local namespace." Use of the "global" keyword doesn't change a variable's namespace, so much as it calls out to the specified namespace. -- CC
