+
+CAR and CDR now return extra values.
+
+The function CAR now returns two values. 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.
