I do not understand what you mean by ,((plist-get plist) property). I am simply lost here. I don't know which parts of that are supposed to be fixed structure and which parts refer to things in the cond* call. > Or, better, allow VARIABLE to be in an arbitrary argument of PRED: I understand that in the abstract. I just don't see any syntax that makes sense to use for it. > ,(PRED ARG1 ARG2 !VARIABLE ARG3 ...) I don't understand this syntax. `!' as no special meaning. It cam't magically have a special meaning in a cpnd* pattern. It would be part of the variable name. This feature makes sense, and I've defined a syntax for it already: (constrain VARIABLE (PRED ARG1 ARG2 VARIABLE ARG3...)) -- 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)
