Possible Solution
You can add a custom PHPDoc with the correct code, but it seems a bit redundant.
#233 (comment) has an example of this.
/** * @param callable(RequestInterface): Promise<ResponseInterface> $next * @param callable(RequestInterface): Promise<ResponseInterface> $first * * @return Promise<ResponseInterface> */ public function handleRequest(RequestInterface $request, callable $next, callable $first): PromiseAdditional context
Seems #234 is already on the way to get it fixed!
But I could hardly find ANY information about "issue". So creating a new issue for documentation purposes.
