That's odd.  My experience from trying to learn ocaml at one point was
that the tuple notation is preferable because you can do pattern
matching on every value in the tuple whereas with the other one you
can match on either the first or second parameter but not both without
nesting ocaml's version of 'case ... of' (match ... with?).  One of
the things I really like about Haskell syntax is that you can pattern
match on any number of parameters without having to nest 'case ... of'
