I'm replacing macros with static inline functions to avoid issues like this one (ex: bpo-35059). Are you interested to convert the PyObject_TypeCheck() macro to a static inline function?
"""
There is a lot of macros like:
#define PyObject_TypeCheck(ob, tp) \
(Py_IS_TYPE(ob, tp) || PyType_IsSubtype(Py_TYPE(ob), (tp)))
These work fine until an argument happen to contain a comma.
"""
This macro also has a common bug of macros: if one argument has a side effect, it is executed twice! For example, if an argument is a function call, the function is called twice.
