Error response shouldn't use return

[jclee100]

In Wiki: Responding With An Error it states:

return $this->response->errorUnauthorized();

However, all the method does is throws an error. The method itself has no return statement. Isn't the return redundant?

Consider the following controller method as example. If a return is added to the errorResponse, it does nothing except adds a warning to the IDE because there's a conflict between return void and the declared return type. (Adding |void to @return causes a warning too.)

/**
 * Display the specified resource.
 *
 * @param  \App\Letter $letter
 * @return \Dingo\Api\Http\Response
 */
public function show(Letter $letter)
{
    /** @var User $user */
    $user = $this->auth->user();
    if( $user->cannot('view', $letter) ) {
        $this->response->errorUnauthorized();
    }

    return $this->response->item($letter, new LetterTransformer);
}
