[Pitch #2] Async/await

One thing I'm missing in this proposal - await must be used in an asynchronous context, so how do you get into such a context? The only example I can find in the proposal is being inside an async function, which looks like a chicken and egg situation.

That's the purpose (one of the purposes) of Task.runDetached, which is defined in: https://github.com/DougGregor/swift-evolution/blob/structured-concurrency/proposals/nnnn-structured-concurrency.md#detached-tasks

There's also @asyncHandler which will be getting it's own proposal soon AFAIR.
