if

Output.apply()

takes an async function as well, that might be the right thing? I'm not sure it can

Yes - it can. Specifically the function returned from the callback passed to

apply

can return a Future and it will be awaited as part of resolving the Output.

does it have to be a

Future

or any awaitable?

Any awaitable. See specifically https://github.com/pulumi/pulumi/blob/master/sdk/python/lib/pulumi/output.py#L41

oh cool! I've had the problem where python will yell because pulumi will

await

on stuff more than once, which breaks with bare `coroutine`s (but not `Future`s based on them)
