OCaml's type inference is truly amazing, makes it such a delight to write statically typed code - reading it on the other hand...

But I think that's easily solved by adding type annotations for the return type of methods - annotating almost anything else is mostly just clutter imo.

Annotations would be a substitute for writing the return type. Extra code for a shortcut seems like the worst solution.

    I don't mean Java annotations, those would be too clunky - in OCaml a type annotation is really just adding `: <typename>` to variables, function return types, etc.

    so fibonacci could look like this

    ```

    let rec fib n =

      match n with

  | 0 -> 1

  | 1 -> 1

  | _ -> fib (n - 1) + fib (n - 2)

    ```

    or with annotations it becomes this:

    ```

    let rec fib (n: int): int =

      // Same as above :)

    ```
