    Maybe this helps wrapping your had around the start-suspend-resume-return circle:$fiber = new Fiber(    function($one) {        $two = Fiber::suspend($one);        $three = Fiber::suspend($two);        $four = Fiber::suspend($three);        $five = Fiber::suspend($four);        $six = Fiber::suspend($five);        return $six;    });print $fiber->start(1);print $fiber->resume(2);print $fiber->resume(3);print $fiber->resume(4);print $fiber->resume(5);print $fiber->resume(6);print $fiber->getReturn();//prints 123456
