I would like to get back to the discussion about interfaces and signature type declarations at some point, and a syntax dedicated to declaring interfaces is high on my wish list. In the mean time, if you need interfaces today, I think using metaclasses would be easier than using a block-statement (if it were even possible using the latter without passing locals() to the generator). -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
