I think that's a great idea.

One good thing I can say for the Enumerator/Iteratee nomenclature is that it nicely connotes the inversion of control (i.e., the "push" data flow) that enumerator is all about. Enumera*tor** *feeds Itera*tee* -- subject, verb, object. Producer/Consumer connotes the same by allusion to the producer-consumer pattern of thread synchronization.
