I think the previous code for `Coend` was incorrect. The previous code was in no way different from the code for `trait PolyFunction1`, i.e. for `End`. The existential quantifier is encoded in Scala as a case class with an extra type parameter.

An existential quantifier is encoded in Scala as a case class with an extra type parameter. An universal quantifier is encoded as a trait with a method having a type parameter.
