Can you tell me how do you use those customizations (i.e. formatvarargs, formatarg and other arguments of formatargspec)? >> I'm not sure how __repr__ should look like.

If it's a method, than no matter how its first parameter is named - it will be omitted. Same applies for classmethods. - Yury _______________________________________________ Python-Dev mailing list [email protected] http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
