this isn't exactly what you ask for, but it gives a similar result. it's
kind of obvious, but it's possible you didn't know methods were first
class entities.
class Foo:
def __init__(self, useBar=False):
if useBar:
self.foo = self.__bar
else:
self.foo = self.__foo
def __foo(self):
print('foo')
def __bar(self):
print('bar')
