+;; Using the Simple-Syntax System
+;; 
+;; The syntax for defining macros in this system is similar to that for defining functions. In fact if the macro has a fixed number of arguments the syntax is identical. For example:
+;; 
+;;   ; Define a simple macro to add a value to a variable.
+;;   ;
+;;   (define-simple-syntax (+= variable value)
+;;     (set! variable (+ variable value)))

+;;   (+= v 7)
+;;   v ; => 9
+;; 
+;; For a fixed number of arguments followed by an unknown number of arguments we use ... after a single argument to represent the unknown number (possibly zero) of arguments. For example, let's revise our definition of += to allow zero or more values to be added:
+;; 
+;;   ; Define a simple macro to add a zero or more values to a variable
+;;   ;
+;;   (define-simple-syntax (+= variable value ...)
+;;     (set! variable (+ variable value ...)))
+;; 
+;;   ; Use it
+;;   ;
+;;   (define v 2)
+;;   (+= v 7)
