I was genuinely relieved. Finally, there was going to be a way out of completion handler pyramids, delegate chains, and the special kind of cognitive overhead that comes from reading code that executes in a completely different order than it is written. I had worked with C# async/await years earlier, and my mental model came from there. In a UI app, if a SynchronizationContext is present, awaiting a Task captures it and posts the continuation back to it.
