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 !
