You can of course fake up several logical iterators on top of that
single iterator by buffering some or all of the keys, which is no
worse than what keys and values do at the moment.
Note that I explicity didn't suggest making different instances of
each on the same hash use different iterators because I decided it
probably wasn't doable.
