Not clever... facetious. Of course Enumerator is useful, and with 1.9
fairly elegant. But rather, the question is why we must do

  enum.each_slice(2).map {|a,b| ...}

when

  enum.map {|a,b| ...}

could be made to work. This is especially interesting b/c it seems the
underlying implementation stands to be simpler and faster by doing so.
