What about just supporting out-of-line keys?  If somebody wanted the key 
to be part of what they were iterating, they could still have the object 
contain the key.

With that said, wouldn't a persistent hash map be better done in local 
or session storage?  I really think we should drop one of these 
concepts.  I don't presently have a strong opinion on which.
