I'm so glad you said this, I'm sorta burned out right now trying to
read all this, and I got sorta confused by that part. But what you're
saying is what I thought I understood.

Okay, now your example is pretty interesting. I guess it makes sense
that iter() returns a type iterator. Sure, of course.

Thanks as always to everyone, this is a trove. I'm a bit under the
weather so I'll have to come back and read it closer. I'm a little
clearer, though, and not just on iterators...
