(The mysterious undocumented Iter class...)
Iter.count(iterator)
but remember the iterator is consumed by the calls and is
.hasNext()==false afterwards.
Iter has many things for iterator. Filter, map, transform, reduce,
fold, concat, ...

I found myself writing an iteration down an iterator just to count the
things it covered. Firing up ARQ for count(*) seemed like overkill.
Would it be reasonable to suggest that the listX apis have
corresponding countX, or that iterators be prepared to return a count?
