You are asking too much of the assignment operator. You must 
remember that Ocaml does not support operator overloading, 
so you cannot define a
val (:=) : 'a ref -> 'a -> unit

and a
val (:=) : ('a * 'b) ref -> ('a * 'b) -> unit

This would require a form of "generic overloading" of (:=) 
over all tuple types. This is really a little too much, I think.

BTW, are you sure you need references?
