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.
