Hi, I'm reading the django's source code, and I am quite confused by https://github.com/django/django/pull/812/files and https://code.djangoproject.com/ticket/19872#no2
-- Why @cached_property need to return self when access from class? https://docs.djangoproject.com/zh-hans/2.0/_modules/django/utils/functional/#cached_property
I see this PR for sure can make @cached_property behave like python's @property, I have tested by myself here: https://gist.github.com/laixintao/f1114d964c19679c973c2c3c3f1fa8ba#gistcomment-2631456 , but still I can think out one useful situation.
Can somebody provide a condition that @cached_problem will cause problems without return self when access from class?
