[ANN] checked_oint v0.1.0

I’d like to announce a new library: checked_oint. It implements checked arithmetic for both signed and unsigned integers of 8, 16, 32, 64, and 128 bits. Unlike stdint or ocaml-integers, routines in this library either return an option or raise an exception when a result of an arithmetic operation cannot be represented in a desired integer type. In addition, it contains abstractions for manipulating arbitrary integers and integer types in a generic and type-safe manner, which I find quite useful for compiler/interpreter implementations.

Usage example:

open Checked_oint

let () =
  let x = U8.of_int_exn 50 in
  let y = U8.of_int_exn 70 in
  assert (U8.equal (U8.add_exn x y) (U8.of_int_exn 120));
  assert (Option.is_none (U8.mul x y))

Feel free to ask any questions in the comments.
