As I explained in my previous reply to Paul - I did not expect for-in
to support everything I use with Iterators. I simply wanted to find
out if the for-in implementation is going to clash with my idea of
implementing GetIterator() in RTL's container classes. So far I don't
see any problems, and I can't see why we can't implement both. There
are use-cases for both.  I see for-in as a "lite" version of Iterator,
but I still have a need for a more "full" implementation as well -
supporting a larger method interface.

Java uses both, that is why I asked. But yes, I kind-of expected them
to be the same thing, but just wanted to make sure.
