What about this? Define a base class AllowDynamicCall:

class AllowDynamicCall(object):
     def __call__(self, *args, **kwargs):
         return self._callfunc(self, *args, **kwargs)

And then subclass AllowDynamicCall:

class Example(AllowDynamicCall):
     def __init__(self):
         self._callfunc = lambda s: s
