The next step would be to use coroutines so the logic of a longer-running
task, which has to wait for other events at multiple points, can be
written in a single linear stream without having to be fragmented into
multiple callbacks.

Yes, indeed.

Actually, if you know Simula, coroutines are inherent part of that
language, and they based their yet more advanced process-oriented
model on these. I find it amazing what Simula provided (in 1967!)
to support such things. Object orientation[*], coroutines, etc.,
all fit together, powerful, and in a neat syntactical form. - But
"no one" is using Simula, and my friend was using C++; don't know
what C++ supports in that respect today. I know that he implemented
the "simulation" parts (queuing, time-model, etc.) in C++ himself.

[*] It was the language who invented Object Orientation - quite
naturally a concept from the simulation perspective -, but they
neither invented nor used the term "OO"; probably because it was
much more than that what they provided.
