New issue 2400: PyPy 3.5 operator requires modification https://bitbucket.org/pypy/pypy/issues/2400/pypy-35-operator-requires-modifi... Connor Shearwood: The `operator` module in `pypy/modules` is currently incomplete. It currently attempts to merge the behaviour of CPython's stdlib `operator` and `_operator`. As the lib-python version of `operator` imports from `_operator`, the pypy specific `operator` should be renamed to `_operator` and emulate the functionality from CPython's `_operator`. This will reduce the amount of reimplementation (the existing `interp_operator` already implements most/all of `_operator`) whilst allowing conformance to the existing implementation. This will also fix `hmac` on pypy 3.5, as it depends on `operator._compare_digest` which is currently unimplemented.
