 ## Swift 5
 
  While behaviour is identical, Swift 5 is unable to inherit actor isolation through the new `#isolation` keyword ([SE-420](https://github.com/swiftlang/swift-evolution/blob/main/proposals/0420-inheritance-of-actor-isolation.md)) so an `isolated` reference to the current actor must always be passed.
