-type 'a t
-(** Count items of type ['a]. *)
-
-val create : unit -> 'a t
-(** Create a new counter. *)
-
-val incr : 'a t -> 'a -> unit
-(** [incr counter thing] adds one to the count of [thing]s in [counter]. *)
-
-val decr : 'a t -> 'a -> unit
-(** [decr counter thing] subtracts one to the count of [thing]s in [counter]. *)
-
-val add : 'a t -> 'a -> int -> unit
-(** [add counter thing n] adds [n] to the count of [thing]s in [counter]. *)
-
-val sub : 'a t -> 'a -> int -> unit
-(** [sub counter thing n] subtracts [n] to the count of [thing]s in [counter]. *)
-
-val set : 'a t -> 'a -> int -> unit
-(** [set counter thing n] sets the count of [thing]s to [n]. *)
-
-val get : 'a t -> 'a -> int
-(** [get counter thing] returns the count of [thing]s. (Returns 0 for
