Say I have a file mod.ml with
let hello_world () = print_endline "Hello World"
Then I have main.ml
open Mod
let () = hello_world()
That works fine. Now let us write module explicity and change mod.ml to
module Mod =
struct
let hello_world () = print_endline "Hello World"
end
Now when compiling main.ml I get
Error: Unbound value hello_world
I also tried by inserting a signature into mod.ml but to no avail.
What am i doing wrong here?

Thanks,
Manfred
