I'm not much of an OCaml expert, but I suspect that what you are trying to do
is not possible.
Imagine that you had defined such a function, and want to call it like this:
> myFunctionCall f l
What would be the type of f? It depends on l:
If l is [], f has type 'a
If l is [1], f has type int -> 'a
If l is [1; 2], f has type int -> int -> 'a
etc.
I don't think OCaml can properly type a function like you are describing.
Regards,
Jim
