The API in 2.7 shouldn't be changed.
The error message can be fixed though.
Also, it is not clear that the API should change even in 3.3. The list.index() method is not required to accept None. It is not different than other APIs that use PyArg_ParseTuple() with an "i" field for a start, stop, or step argument.
