it does not necessarily mean that the word "self" should be explicitly used to induce circular references. Instead of accessing the ARR variable through the property Self.arr, we change the code to access it through the instance variable _arr, as follows:As a result we know that even if "self" is not explicitly present in your block code, a circular reference will appear! As long as you use the self-possessed thing in the block ! But for this situation, I don't know how to rule out circular ref
