Assuming your "super" was really "super *args", this should print:

  more
  1
  hello world
  2
  test

same as if the renaming method was being used (maybe this is how Ruby
could implement it behind the scenes).

The mix-ins would be chained to avoid the problems of multiple
inheritance, so the order of inclusion would be important.
