<?php

use function Async\spawn;

$coroutine = spawn(function() {
    suspend();
    return "done";
});

suspend(); // let the coroutine start and suspend

var_dump($coroutine->isSuspended()); // bool(true)
var_dump($coroutine->isStarted());   // bool(true)
var_dump($coroutine->isCompleted()); // bool(false)
