Handling tasks that produce results

I don’t see an equivalent of asyncio’s wait(return_when=FIRST_COMPLETED) API in anyio. Is that a deliberate omission, and if so, how should I write code that runs background tasks and processes the results as they arrive? More generally, the documentation doesn’t seem to cover getting the return value of a task at all.

Is the intention that tasks only return values via streams? For my use cases, streams seem very heavyweight - or am I missing something?

It’s quite likely that this is a documentation issue rather than a functionality issue, and it may even be that all that is needed is for beginners to be pointed at a “how to get started thinking in terms of async” document. But I’m struggling to find such a thing, and I feel like I’m ending up writing my own low-level utilities, when I expected async to let me focus more on the higher level tasks.

Btw there’s with anyio.open_signal_reciever() as channel: that might help

I really shouldn’t be writing code when I’m sleepy. I’ll amend it to actually help with the requested task.
