I don't see why anyone would use anything other than your Info:

   function Info (Item : in T) return Value;

You may need to pass values of T'Class (or access T'Class) around, but
this shouldn't affect the primitive. And it seems to me it makes it much
simpler from a teaching point of view (but IANAT!)
