Almost.  This means that we're retroactively saying that all objects
with a next method are iterators, thereby slightly stomping on the
user's namespace.  But as long a you don't use such an object as an
iterator, it's harmless.

And if my position wasn't clear already, I agree it's not worth
"fixing". :-)
