Well, there you go. There *is* something wrong with having six variables 
called 'q'.

Namespaces and scopes are work-arounds for the fact that, while there are 
an infinite number of possible names, most of the good ones are already 
taken.

Namespaces and scopes mean that I can use a name "q" even though I've 
already used it for something else, but there is still cost to re-using 
names (even if that cost is sometimes trivial).
