Why should

   (x for x in [1, 2, 3])

be a valid coroutine but

   iter([1, 2, 3])

not?

Anyway, calling close() on an iterator can be a necessary requirement
even in ordinary generator usage. Only now they have to know if the
underlying iterator was sired by a generator or some other constructor.
