The only one I found is [`Task.withUnsafe(Throwing)Continuation`](https://github.com/DougGregor/swift-evolution/blob/structured-concurrency/proposals/nnnn-structured-concurrency.md#low-level-code-and-integrating-with-legacy-apis-with-unsafecontinuation) in this pitch.

```swift
Task.withUnsafeContinuation { continuation in
  ...
  if ... {
    continuation.resume(returning: returnValue)
  } else {
    continuation.resume(throwing: error)
  }
}

```
