I don't understand.  Iterators are an internals-neutral interface.

(If you need to have a sorted container, then a balanced tree is a
better choice than a hash table.)

Well, if it is not used frequently, I guess it wouldn't matter.

Most of the time you can just export the iterator of the underlying
container (this does not mean exposing the internals directly).  The
only situation where you'd get hairy code is when the mapping from the
internal sequence (as given by the underlying container's iterator) to
the returned sequence is nontrivial.
