Since it has to go to the +trouble to figure out if the object is carcdr-able anyway, we figured +you might as well get both halves at once. For example, the following +code shows how to destructure a cons (SOME-CONS) into its two slots +(THE-CAR and THE-CDR): + + (MULTIPLE-VALUE-BIND (THE-CAR THE-CDR) (CAR SOME-CONS) ...) + +For symmetry with CAR, CDR returns a second value which is the CAR of +the object. In a related change, the functions MAKE-ARRAY and CONS +have been fixed so they don't allocate any storage except on the +stack. This should hopefully help people who don't like using the +garbage collector because it cold boots the machine so often. -- cgit v1.2.3
