That looks like new syntax to me. Did I miss your point? I have no strong leaning about what the exact syntax should be for programming by contract. The syntax you show above seems reasonable, except that I am not sure about requiring that everything be put inside parentheses. That seems a bit confining for more complex conditions. -- http://mail.python.org/mailman/listinfo/python-list
