Module Container

module Container: sig .. end

The idiom for using Container.Make is to bind the resulting module and to explicitly import each of the functions that one wants:

      module C = Container.Make (struct ... end)
      let count    = C.count
      let exists   = C.exists
      let find     = C.find
      ...

This is preferable to:

      include Container.Make (struct ... end)

because the include makes it to easy to shadow specialized implementations of container functions (length being a common one).

Container.Make implements iter in terms of fold, which is often slower than implementing iter directly.

module type T = sig .. end

val fold_count : ('a -> init:int -> f:(int -> 'b -> int) -> 'c) -> 'a -> f:('b -> bool) -> 'c

module Make: functor (T : T) -> sig .. end

module type S1_phantom_invariant = sig .. end

module type Generic = sig .. end

module type Generic_phantom = sig .. end

module Check: functor (T : T.T1) -> functor (Elt : T.T1) -> functor (M : Generic  with type 'a t := 'a T.t  with type 'a elt := 'a Elt.t) -> sig .. end

module Check_S0: functor (M : S0) -> Check(sig
type 'a t = M.t 

end)(sig
type 'a t = M.elt

type 'a t = 'a M.t

type 'a t = M.elt

type 'a t = 'a M.t

type 'a t = 'a

type 'a t = ('a, Container.phantom) M.t
