Yes. That's the "async flow" library thats been mentioned in this or
a related thread.

Yes. The separation of async into a separate library/framework is the go.

While your comments I agree with, they read as if sync/async is a developers
I'm assuming that's accidental?

I feel as if we have clarified one thing; there can be no iostream input
over async sockets (the function signature is blocking). Which leaves the
operators and whether iostream output operators over async has any value?
