cross :: [a] -> [b] -> [(a,b)]
It's just kind of a pain (you build [(a,(b,(c,d)))] and then flatten
out the tuples). The applicative notation is a neat little trick
which does this work for you.
It seems to me like this would all be easy if (a,b,c,d) was sugar for
(a,(b,(c,d))), and I can't see a disadvantage to that.
No disadvantage aside from it making tuples indistinguishable from
lists.
