thanks for the pointer. Then I guess the documentation could be improved by e.g. saying something similar to: [...] The self parameter of a method of an extension type is guaranteed never to be None. (Note: arithmetic methods might be an exception to this rule. [http://docs.cython.org/src/userguide/special_methods.html#arithmetic-methods]).
