If and when such a mechanism is in place for us free software activists, we might agree that open-paren-in-column-0-is-defun-start is not worth while any more. But it appears that has not happened yet, so I think that the open-paren-in-column-0-is-defun-start guided heuristic IS still worth while for us. -- Dr Richard Stallman Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
