 * This class indicates a successful operation with no (relevant) data

 * For example a command that either succeeds or throws an exception would look like this:
 * `public function interpret(RawResponse $response): null`, which is not valid.
 * Instead we use this class so that we get:
 * `public function interpret(RawResponse $response): Success`
