This exposes
_PyObject_LookupSpecialMethod()astypes.lookup_special_method(obj, attr).I am not quite sure which one between the two similar funtions in
Objects/typeobject.cshould be preferred to be exposed:_PyObject_LookupSpecial()or_PyObject_LookupSpecialMethod(). I chose the_PyObject_LookupSpecialMethod()because it is the function that is called byLOAD_SPECIAL. So I suppose using this one is more consistent with the CPython interpreter when parsing with-statements (#144386 (comment)).However, I am open to adjusting the PR to expose
_PyObject_LookupSpecial()instead if that one is more suitable.📚 Documentation preview 📚: https://cpython-previews--144990.org.readthedocs.build/
