Note:
resume gets the return value,
If there is a corresponding yield in wait resume, then the yield parameter is used as the return value of the resume. The first return value indicates that there is no error in the coroutine. The number of subsequent return values and their values depend on the yeild parameter.
If there is no yield in wait, then the return value is the corresponding function's return value,:true,* * *
