But not an array?!

irb(main):005:0> (0..10).to_a.values_at([2, 3, 4, 5])
TypeError: can't convert Array into Integer
        from (irb):5:in `values_at'
        from (irb):5
        from :0

This seems a little inconsistent, it would seem better if it handled
any arguments which were enumerables containing integers.
