class Socket {
  // ...
  public var alive: Bool {
   @asyncHandler get { // would this work?
      let handle = detach { await self.checkSocketStatus() }
      return await handle.get()
      //     Would this work?
    }
  }

  private func checkSocketStatus() async -> Bool { /* ... */ }
}

If we had @asyncHandler would the above example still be a motivation?

I am more familiar with languages that do not support async properties so I am on the fence about its utility. Personally I feel that it makes Swift harder to reason about.

Let’s say I have to interact with an sdk property that is async only. What are the mechanisms available to me to be able to call this property if I am not in an async context?
