Implement Enumerator#+ and Enumerable#chain [Feature #15144]
They return an Enumerator::Chain object which is a subclass of Enumerator, which represents a chain of enumerables that works as a single enumerator.
e = (1..3).chain([4, 5]) e.to_a #=> [1, 2, 3, 4, 5] e = (1..3).each + [4, 5] e.to_a #=> [1, 2, 3, 4, 5]
