I think you misunderstand. This would only be part of the internal Cython ABI. If you use public/api functions, or take the pointer to the function, you get the C semantics (possibly with unraisable exceptions). The details are in the CEP, this would only replace the extra 'error' argument to cdef functions. _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
