 /**
  * Process an incoming request and/or response.
  *
  * Accepts a server-side request and a response instance, and does
  * something with them.
  *
  * If the response is not complete and/or further processing would not
  * interfere with the work done in the middleware, or if the middleware
  * wants to delegate to another process, it can use the `$out` callable
  * if present.
  *
  * If the middleware does not return a value, execution of the current
  * request is considered complete, and the response instance provided will
  * be considered the response to return.
  *
  * Alternately, the middleware may return a response instance.
  *
  * Often, middleware will `return $out();`, with the assumption that a
  * later middleware will return a response.
  *
  * @param Request $request
  * @param Response $response
  * @param null|callable $out
  * @return null|Response
