The property modelClass does not exist. Did you maybe forget to declare it?

It seems like $like defined by parameter $like on line 79 can also be of type boolean; however, rhosocial\base\models\traits\EntityQueryTrait::guid() does only seem to accept false|string, maybe add an additional type check?

It seems like limit() must be provided by classes using this trait. How about adding it as abstract method to this trait?
