I think I see what the confusion is. Your version of recursive looses
all the nested structure of the original. And so works fine for most
cases, as long that is what one wants/expects. I've been trying to do
it such that the nested structure stays intact. e.g.

  [3,2,1,[6,5,4,[9,8,7]].recursive.sort  #=> [1,2,3,[4,5,6,[7,8,9]]

Your method produces:

  [3,2,1,[6,5,4,[9,8,7]].recursive.sort  #=> [1,2,3,4,5,6,7,8,9]

The former proves much more difficult.
