I was reading up on function attributes. Incredible new feature... You can 
now add member functions to classes and class instances without having to 
inherit from them. Can be done at runtime!

Look what you can do with them
from cPickle import loads, dumps, UnpickleError

def unpickle(maxbytes):
        data = self.sock.recv(maxbytes)
        return dumps(data)

def pickle(anything):
        """anything can be a list, dictionary, tuple, string.. you name it
        data = loads(anything)

def patchSocket(instance):
        pickle.sock = unpickle.sock = instance
        instance.pickle = pickle
        instance.unpickle = unpickle

sock = socket(...)

patchSocket(sock) # adds new member methods : pickle and unpickle
