Functions (including methods) are objects, and can be referenced and
bound like any other object::

    >>> import random
    >>> class OptionDispatcher(object):
    ...     def option_a(self):
    ...         print "option a"
    ...     def option_b(self):
    ...         print "option b"
    ...
    >>> dispatcher = OptionDispatcher()
    >>> choice = dispatcher.option_a
    >>> choice()
    option a
    >>> choice = dispatcher.option_b
    >>> choice()
    option b
    >>> options = [dispatcher.option_a, dispatcher.option_b]
    >>> choice = random.choice(options)
    >>> choice()
    option a
    >>>
