I see, thanks.

I think that want a little too much from Ruby.
In OCAML e.g it would not be possible to recognize
tuples as return values and then "curryfy" them in
a general way (i.e handling tuples of any size),
because of the static type safety.)
In Ruby, it would be possible, but requires some
ugly hacking.
