Subject: [Caml-list] Sample code doesn't work
Hi,

I have a problem with the following simple example:

let rec make_account wert0 = 
  let wert = wert0 in
  let add wert_ =
    make_account (wert+.wert_)
  in   
  let sub wert_ =
    make_account (wert-.wert_)
  in 
  let get () = 
    wert 
  in
  (add, sub, get);;

When trying to evaluate this I get the error message:

This expression has type
  (float -> 'a * 'b * 'c) * (float -> 'a * 'b * 'c) * (unit -> float)
but is here used with type 'a * 'b * 'c

How can I make this work?
