Sounds great. Since the functionality is a direct generalization of
transform_iterator, I'd prefer to use the name transform_iterator and
either (a) switch entirely to your combining_iterator implementation or
(b) give transform_iterator_generator the brains to switch between your
implementation and the existing implementation based on the number of
iterators being adapted.
