This is slightly related to a feature I'd like that's easy to do in lisp, but I don't think there's a way to do it in ML-style languages:

I have a function that returns a tuple, and a function that takes two curried parameters.  I'd like to pass the results of the first to the second, without having to break up the tuple with fst and snd (or pattern matching).

let f () = (1,2)
let g x y = x + y

g (? f ())

vs.

let x,y = f () in
g x y

With lisp you can just "apply" and it works.  There's no way in caml to spread the arguments into a curried function application, however.

Chris
