Create an extension class which wraps "complicated" (init1 and get_n)
are a complicated constructor and member function, respectively.
>>> c1 = complicated(s, 99)
>>> c1.get_n()
99
>>> c2 = complicated(s)
>>> c2.get_n()

a quick regression test for a bug where None could be converted
to the target of any member function. To see it, we need to
access the __dict__ directly, to bypass the type check supplied
by the Method property which wraps the method when accessed as an
attribute.
>>> try: A.__dict__['name'](None)
... except TypeError: pass
... else: print('expected an exception!')
>>> a = A()
>>> b = B()
>>> c = C()
>>> d = D()
>>> take_a(a).name()
'A'

... take_b(a)
... except: pass
... else: print('no exception')
>>> try:
