Subject: Re: [Caml-list] Odd Type Checking Problem
Beginner's opinion:
I think that the compiler/interpreter is clear: 
	'a->'b->'a 
	is not 
	'a->'a->'b->'a
and that you just let the function starve before giving it the last meatball.
Look:
# let mAny: 'a -> int -> 'a = fun succ0 input -> succ0 in
     let ans0 = true in
     let x = mAny (mAny ans0 1) in
         x 2;;
      - : bool = true
