Aside from the answers coping with your actual problem, you don't have really a problem having to do with your "first module" or a module at all, but incidentally while we're here I'll remind you that you probably shouldn't pollute the main namespace in modules, but put an explicit package in them, exporting only what you really need, or better giving the user choose what he really needs to export.

Also incidentally, even if this was just a minimal example, all lowercase modules are reserved for pragmata.
