Precisely how to indicate one is a detail, and I've proposed three ways to design that: * A clause with one element. * A clause that starts with t. * A clause that starts with nil. * A keyword. If you have preferences about that detail, please let me know. I am also interested in other suggestions, but I will only accept it if it is as natural and simple as those above. -- 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)
