An alternative I am fond of is to to avoid introducing a new type, and simply initialize a PyObject * and register its address. For example:
PyObject *tmp; static PyObject *s_update; // pick a naming convention
PY_IDENTIFIER_INIT(update); tmp = PyObject_CallMethodObj(result, s_update, "O", other);
(but also PyObject_GetAttr(o, s_update), etc.)
I like this better too because of the all-caps macro name. Something about seeing "Py_identifier" look like a function call and having it add the magical PyId_update local bugs me. It just looks wrong, whereas the all-caps is more of a cultural clue that something else is going on. -Barry
