Sure, you're right in this case, but I don't tend to write code that way.
In files it would tend to be something like

let foo() =
        print_int;
        let f x = x + 1 in
        f 3;;
File "foo.ml", line 2, characters 8-17:
Warning: this function application is partial,
maybe some arguments are missing.

On the command line I would break it up with ;;'s:

# print_int;;                                 
- : int -> unit = <fun>
# let f x = x + 1 in f 3;;
- : int = 4
