+Inside a generator function, the ``return`` statement when used without a
+value signals the end of the procession of values; after executing a
 ``return`` the generator cannot return any further values.  ``return`` with a
-value, such as ``return 5``, is a syntax error inside a generator function.  The

 You could achieve the effect of generators manually by writing your own class
 and storing all the local variables of the generator as instance variables.  For
