"data X = 1": "Illegal literal in type (use DataKinds to enable): 1"

This error message is not good. "1" is not in a type position, and DataKinds will not help anything. Well, except the error message, which with DataKinds enabled is instead

parse error in constructor in data/newtype declaration: 1

If it's not hard, we should give that error message also when DataKinds is disabled.
