To remove it would break old Emacs Lisp programs in a way that is very hard to fix. With most of our incompatible changes, it is easy to find the things that need to be fixed. So it is not such a big obstacle to running old programs. This would make old programs useless. Mere simplification can't justify that. This is not a mere "novelty". -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
