TODO: Steve Fink sayd:
And if there were a keys() method, then 'defined' and 'exists' are
very different. (And there ought to be, and would be if we weren't
all ignoring Leo's iterator proposal.)
I need to read that proposal :-)

Looks like the proposal got accepted? I see iterator.c and
read the recorresponding tests... I went ahead and used it.
Is that cool?
