I think that's (from a language user's point) the "wrong" question. These types are not designed to be very much visible for the user, but more like helpers. (Please correct me if I'm wrong here). > And also how does one specify a Rat vs a > Num or what does "18.2" or "4/3" actually get you? I think that S03 elaborates on that. See also my example above.
