func justAnExample<T : RawRepresentable>(_ enumType: T.Type) where T.RawValue == Int {

  // Note that an explicit use of init is required when creating an instance from a
  // metatype. We're also using a guard, as `init?(rawValue:)` is failable.
  guard let val = enumType.init(rawValue: 0) else { return }
  print("description: \(val)")
}

justAnExample(Foo.self) // prints: "description: Hello Foo"
justAnExample(Bar.self) // prints: "description: Hello Bar"
