Why can’t for-of be applied to iterators?

I agree, FWIW.
I think I would go farther and suggest that _only_ iterators be
iterable. That way, the RHS of a for-of is expected to be an iterator.
In the worst case you end up having:
var a = [1, 2, 3, 4]
for (let x of values(a))
for (let x of a)
which to my eye is better anyway. Making an "itertools"-like library
difficult is a definite drawback of the current spec.
