* The enumerator has with_index.
* So ary.map.with_index works as follows.
*
* p [1,2,3].map.with_index {|o, i| o+i } #=> [1, 3, 5]
* p %w[foo bar baz].map.with_index {|w,i| "#{i}:#{w}" }
* #=> ["0:foo", "1:bar", "2:baz"]
*
* An enumerator object can be used as an external iterator.
* I.e. Enumerator#next returns the next value of the iterator.
* Enumerator#next raises StopIteration at end.
*
* e = [1,2,3].each # enumerator object.
* e = [1,2,3].each # returns an enumerator object.
* p e.next #=> 1
* p e.next #=> 2
* p e.next #=> 3
