Add a new experimental "_Py_CAPI2" API: opt-in which doesn't leak implementation details and replace macros with function calls. The defined is called "_Py_CAPI2" and not "Py_CAPI2" because it must not be used at this stage. The new API is experiment and can be removed anytime. With this API, PyTuple_GET_ITEM() macro becomes a function call and the implementation uses assertions to check if the first argument is a tuple and that the index is valid. It should help to investigate bugs when Python is compiled in debug mode.

According to discussions on python-dev, a PEP will be needed first. Moreover, I prefer to make some progress on https://bugs.python.org/issue35134 before. I close the PR. |
