code: public function runWild(){
          foreach ($this->handlers as $handler){
              $rtn = $handler instanceof Closure ? $this->context->call($handler,$this->req) : $this->context->callInClass($handler,$this->action,$this->req);
              if (!is_null($rtn)) return $rtn;
          }
          return null;
      }
