I'm using the new names introduced by SE-0006

The protocol is not called Iterator to disambiguate it with the
Iterator associated type in Sequence from the protocol:

protocol Sequence {
  associatedtype Iterator : IteratorProtocol

It is not called Iterable because that would have the wrong meaning
(Sequence is iterable, the iterator iterates over its elements).
