We can also fill it later at type initialization. But since we already have #define __Pyx_CyFunction_Call PyCFunction_Call and PyPy version of __Pyx_CyFunction_Call I think it's better to replace define with static function you mentioned above. -- vitja. _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
