The CNil type is used to terminate a 'list' of :+: alternatives.
Like the Nil constructor of List, it does not convey real information. This is achieved by not having any value for CNil.
This makes the type
Int :+: CNilequivalent toInt, because the right (Inr) alternative of:+:can not be constructed properly.
