But that won't compile, because it doesn't obey the syntax rules of
Haskell. You could, however, write

1 : (2 : (3 : End))
Except that (for no particularly good reason) ":" is a reserved symbol
that always refers to the Prelude list version. You could define a
similar name like:
data List x = x :- (List x) | End
1 :- (2 :- (3 :- End))
