I see this operator in SimpleLazyObject here: https://github.com/django/django/blob/1.7/django/utils/functional.py#L330
Also added a test to check if it behaves as expected: https://github.com/django/django/pull/3514

Resolution: worksforme
Status: newclosed

What is more, these tests already exists in https://github.com/django/django/blob/master/tests/utils_tests/test_lazyobject.py
The contains method was added to the code in this commit: https://github.com/django/django/commit/7a698c05b56d7d5e267241dc71c16c403efd2965

So I'm closing this issue as worksforme
