Also, given that languages like C# have similar async/await
functionality, I'd be interested to know how they address questions
like this. If they have a parallel, we should probably follow it. If
they don't that would be further indication that no-one has much
experience of the "best answers" yet, and caution is indicated.

BTW, I'm assuming that the end goal is for async to be a natural and
fully-integrated part of the language, no more "minority use" than
generators, or context managers. Assuming that's the case, I think
that keeping a very careful eye on how intuitive async feels to
non-specialists is crucial (so thanks to Ivan and Yury for taking the
time to respond to this discussion).
