 You could equally write ``for i in generate_ints(5)``, or ``a,b,c =
 generate_ints(3)``.
 
-Inside a generator function, the ``return`` statement can only be used without a
-value, and 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

-the bottom of the function.
+Inside a generator function, ``return value`` is semantically equivalent to
+``raise StopIteration(value)``.  If no value is returned or the bottom of the
+function is reached, the procession of values ends and the generator cannot

 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
