because it help to understand what code actually do. and for what this limit is. Why introduce variable [here](https://github.com/yiisoft/yii2/blob/master/framework/console/controllers/FixtureController.php#L304) ? Because i want code to be understandable by other developers. I also can provide some links to design suggestions by Fowler or other, but i dont like to do it, because people can see it as some bad feature ))
