@erlend-aasland: I'm not sure about this change, so I created a draft PR. It's a part of the PEP 670 implementation. |

In the limited C API version 3.11 and newer, the following functions no longer cast their object pointer argument with _PyObject_CAST() or _PyObject_CAST_CONST(): * Py_REFCNT(), Py_TYPE(), Py_SIZE() * Py_SET_REFCNT(), Py_SET_TYPE(), Py_SET_SIZE() * Py_IS_TYPE() * Py_INCREF(), Py_DECREF() * Py_XINCREF(), Py_XDECREF() * Py_NewRef(), Py_XNewRef() * PyObject_TypeCheck() * PyType_Check() * PyType_CheckExact() Split Py_DECREF() implementation in 3 versions to make the code more readable. Update the xxlimited.c extension, which uses the limited C API version 3.11, to pass PyObject* to these functions.
