I always really thought of Enumerators as representing a sequence with
the logic that produces the sequence being an implementation detail,
but I see that perspective. More importantly, I see the utility of
returning the underlying object in terms of making chained calls using
intermediate methods that produce an enumerator work like regular
iterator chaining.

I'll need to think a bit about how that generalizes to some of the
custom enumerators I'm doing.
