OCaml can warn for these already:

  $ cat unused.mli
  type t
  val x : t

  $ cat unused.ml
  type t = int
  type s = int
  let x = 3
  let y = 4

  $ ocamlc -w A unused.mli unused.ml
  File "unused.ml", line 2, characters 5-12:
  Warning 34: unused type s.
  File "unused.ml", line 4, characters 4-5:
  Warning 32: unused value y.
