That is a clear way of putting it. I was focusing on the questor's

I think you are imagining it backwards....
Huh? ?A for loop is just a while loop with an initialization chunk and
a per-loop chunk at the end of the while block. ?What's weird is that
for allows the condition to be omitted and have an implied "true" put
in its place, but while doesn't allow the condition to be omitted. ?The loop block is not executed
at all if the condition is false, unlike a do/while loop which always
executes the block once. ?But I'm sure you knew that, too.
Right. I was unclear about the case of once-through vs skipping the
payload, but that wasn't the aspect of it that I was trying to
address.
Apologies for muddling the issue. As I said earlier, I should have
taken the time to proof what I read, and in my haste, failed so to do.
