 For calling methods on objects, you can simplify yet further by using the
 :func:`getattr` built-in to retrieve methods with a particular name::

 It's suggested that you use a prefix for the method names, such as ``visit_`` in
 this example.  Without such a prefix, if values are coming from an untrusted

       The decorator syntax is merely syntactic sugar, the following two
       function definitions are semantically equivalent::

       The same concept exists for classes, but is less commonly used there.  See
