From the thread:

  @discardableResult
  public init(priority: TaskPriority? = nil,
      operation: sending @escaping @isolated(any) () async -> Success)

> Take just the operation argument. It's a closure that is sending, escaping, declares any isolation (I don't understand this part very well yet), it's async and it returns Success. That's a whole bunch of facts - 7 to be precise - you need to know about just one parameter of this constructor. I understand that all 7 make sense and there's nothing you can do about it within the current strict concurrency model.
