Or a bit more minimalist:

      else
        [@data] + @kids.collect {|k| k.depthFirst}
      end

This is something you will find about Ruby: you keep thinking of more
compact and clear ways to write the same thing. And if you can't think of a
compact and clear way of writing it, then you write a class to do that
operation for you :-)
