bridging C++ coroutines to Python async ?

[GirasoleY]

I wrote a communication primitive in async coroutine style. And we'd like to explore the possibility to bridge this coroutine style to python land. In torch.distributed the async style is return an object want expose wait() function. I wonder if there's more native way to do so in the binding layer.

Would appreciate some insights on this topic :)

I have never used nanobind with async code. The only relevant discussion is this one: #760
