Something like this:

fiber ctors + swap + assignment + destructor +

fiber.join() =E2=80=93 resumes the fiber (remembers = the context who called it)

this_fiber::suspend() =E2=80=93 yields back to whome= ver called it

this_fiber::switch_to(another fiber) =E2=80=93 direc= t switch to another fiber. the caller context is transferred to the new fiber.


I think at the = moment. execution_context is as minimal and as efficient as it can be.
