`final` `trait` Nothing
  `extends` Any

  /*

  Class `Nothing` (previously named `All` in Scala 2.2.0 and older versions) is - together with class `Null` - at the bottom of the Scala type hierarchy.

  Type `Nothing` is a subtype of every other type (including `Null`); there exist no instances of this type. Even though type `Nothing` is empty, it is nevertheless useful as a type parameter. For instance, the Scala library defines a value `Nil` of type `List[Nothing]`. Because lists are covariant in Scala, this makes `Nil` an instance of `List[T]`, for any element type `T`.
