Umm: huh?  Tom suggested getting rid of del, I suggested it was required 
for some cases in doing testing in the fact of globals (for cases where 
they are the simplest approach), then you suggest that the correct 
approach is to use "del".

Well, I agree (including your point on use of globals, which I attempted 
to anticipate with my comment starting "sometimes"), but I don't really 
see the point of your posting, Duncan...  it appears redundant on all 
counts.
