It's interesting that people refer the same thing with "generators", "semicoroutines" or "stackless coroutines". (A resumable computation that doesn't have a growable stack)

On the other hand, "stackful coroutines" and "coroutines" without a qualifier often refers things with dynamically growing stacks.

It seems to me that the C++ Coroutines refer to the former, which likely complicates the terminology further.
