That's because LISTP doesn't do what LIST? does; it simply checks its input for being either a cons or NIL, so that's the definition of class LIST in CL. If Scheme's LIST? is being used to define a class, that class cannot be a superclass of the class of pairs. -- Even a refrigerator can conform to the XML John Cowan Infoset, as long as it has a door sticker [email protected] saying "No information items inside". http://www.ccil.org/~cowan --Eve Maler _______________________________________________ Chicken-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/chicken-users
