Exception: Cannot get return value of a generator that hasn't returned

[DaisukeDaisuke]

I found an issue with Await::safeRace()
This is probably a philosophical issue regarding the race, as it only occurs in safeRace
Maybe we need exceptions for these bad codes
Note: I discovered this by my mistake

workaround

Catch RaceLostException. Do Not implement race lose yourself

code

<?php
declare(strict_types=1);


namespace daisukedaisuke\test;

use SOFe\AwaitGenerator\Await;

class test{
	private $list = [];
	public function __construct(){
		$this->init();
	}

	public function init() : void{
		$this->race($this->rateChild(0), $this->rateChild(1), $this->rateChild(2));
		$this->reject(0, new \RuntimeException());
		$this->reject(1, new \RuntimeException());
		$this->solve(2, "happy!");//Here is where the exception occurs
	}

	public function rateChild(int $id) : \Generator{
		yield from $this->solver($id);
	}

	public function solver(int $id) : \Generator{
		//This is where the problem occurs
		try{
			yield from Await::promise(function(\Closure $resolve, \Closure $reject) use ($id){
				$this->list[$id] = [$resolve, $reject];
			});
		}catch(\RuntimeException $throwable){
			var_dump("!!");//Squash exceptions!!!
		}
	}

	/**
	 * @param array<\Generator<mixed>> $array
	 * @throws \Throwable
	 */
	public function race(\Generator ...$array) : void{
		Await::g2c(Await::safeRace($array));
	}

	public function reject(int $id, \Throwable $throwable) : void{
		[$resolve, $reject] = $this->list[$id];
		($reject)($throwable);
	}

	public function solve(int $id, mixed $text) : void{
		[$resolve, $reject] = $this->list[$id];
		($resolve)($text);
	}
}

exception

The reason for using the ModuleLoader plugin is for development environments that change frequently
For the production server I will remove the moduleloader and build using Pharynx, creating a single portal phar and auto loader

As a side note, this problem does not occur if the generator is not nested (rateChild => solver)
