What has this to do with the original question of iterating across
integers? What you're now saying is that both the meaning of the
current index and the top boundary can change during iteration; that's
unrelated to whether to use equality or inequality for comparisons.

Oh wait. Rick's back. He's been away so long that I stopped looking
for his name in the headers.
