For some reason functions PyDict_GetItem ( and PyDict_GetItemString ) don't try to check for '__missing__' on subclass, but dict_subscript(dictobject *mp, register PyObject *key) does. Only in this function a failure to get a value using ma_lookup checks afterwards using !PyDict_CheckExact for subclass definition of '__missing__', and then returns a value. Is this intended or just a half implementation ? |

Yes, this is intended. PyDict_GetItem already bypasses user __getitem__ methods, so it's logical it would do the same for __missing__. |
