  I beg to differ. I once wrote a long page dedicated solely to explaining
how the #while loop does and doesn't work, because misunderstandings are
so common:

http://tag.povray.org/povQandT/whileloops.html

  For many non-programmers it's not at all obvious how they work, which
is the reason why mistakes are common, and often a source of obscure errors
for which questions get posted to the newsgroups. Especially nested loops
tend to cause confusion. For a programmer and for people who have used the
while loops it's simple, but for someone who has never used them it might
not be.

  A simple for-loop removes most if not all the confusion.

  And it's not like the for-loop would *replace* while-loops.
