race 与timeout 里
// helper function
function await($task, ...$args)
{
if ($task instanceof \Generator) {
return $task;
}

if (is_callable($task)) {
    $gen = function() use($task, $args) { yield $task(...$args); };
} else {
    $gen = function() use($task) { yield $task; };
}
return $gen();

}

在这个函数里这么调，await 函数永远也不会得到第二个参数。
有一种情况是，当 执行await时，$task为 Syscall对象时，就执行$gen = function() use($task, $args) { yield $task(...$args); }; 此时 $args为空啊，报错。

function race(array $tasks)

return new Syscall(function(AsyncTask $parent) use($tasks) {
    if (empty($tasks)) {

race与timeout 这篇里
// helper function
function await($task, ...$args)
{
if ($task instanceof \Generator) {
return $task;
}

if (is_callable($task)) {
    $gen = function() use($task, $args) { yield $task(...$args); };
} else {
    $gen = function() use($task) { yield $task; };
}
return $gen();

}

await 函数作为array_map的回调函数能接受第二个参数吗？
