+Puts VALUE in location specified by PLACE.  setf! is more general than

+associated with GETTER.

+Example:
+
+ (setf! (car x) 4) <=> (set-car! x 4)
+
+* New syntax: setter GETTER
+The name of the SETTER of GETTER.  The way to associate a SETTER with
+a GETTER is: (setf! (setter GETTER) SETTER)
+
+Example:
+
+  (setf! (setter car) set-car!)
