hello ! i would like to create two types and use the type checker to verify the "meaning" of my programs: type user_id = int type movie_id = int i'd like if the type checker would warn me if i write something that is non-sense: > let a:user_id = 57 and b:movie_id = 80 in if a=b then ... because this is obvioulsy a mistake do you know if is this possible ? thanks by advance ! -- Grégoire
