I think that what defines sequence is an iterator protocol rather than

sequence module could then be a behavior AND a set of functions for
operating on iterators (map, fold, ets)

Are parametrized types ready for prime-time? Like records,
they aren't exactly first-class members of the language, and reading
Richards paper on them, he has some concerns about performance.
