1.9 fix, String is not an Enumerable.

* Removed use of String altogether since all use cases
  are Arrays currently. YAGNI.

* #max_by would have been more elegant, but this way we
  can support 1.8.6.

I made the diff less gratuitous. Don't bloat diffs to meet personal coding style preferences :P
