They are not Lisp functions -- they are implemented as special forms, so as not to always compute all their arguments. That's what makes them useful. What puzzled me about having a function called `xor' is that it is merely an ordinary function on truth values, thus NOT simplar in its use to `and' and `or'. -- 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)
