See http://python.org/doc/current/ref/callable-types.html

Note that the _method's_ __call__ method will be called, not the
class's, so its not exactly what you wanted. However, it's pretty easy
to fake it:

class A:
    def __getattr__(self, name):
        def f(*a, **kw):
            self.notify()
            print 'called %s' % name
        return f

    def notify(self):
        print 'our method was called'


>>> a=A()
>>> a.foo()
our method was called
called foo
>>> a.bar
<function f at 0x40214e64>
>>> a.zork()
our method was called
called zork
>>> f=a.bar
>>> f()
our method was called
called bar
>>>
