PyTuple_GET_ITEM() can be abused to access directly the PyTupleObject.ob_item member:

   PyObject **items = &PyTuple_GET_ITEM(0);

Giving a direct access to an array or PyObject* (PyObject**) is causing issues with other Python implementations, like PyPy, which don't use PyObject internally.

I propose to convert the PyTuple_GET_ITEM() and PyList_GET_ITEM() macros to static inline functions to disallow that.
