>>> class A(object):
...  pass
...
>>> import pickle
>>> from cStringIO import StringIO
>>> src = StringIO()
>>> p = pickle.Pickler(src)
>>> p.dump(A())
>>> datastream = src.getvalue()
>>> dst = StringIO(datastream)
>>> up = pickle.Unpickler(dst)
>>> class A(object):
...     def __init__(self):
...             self.a = 1
...     def hi(self):
...             return 'hi'
...
>>> obj = up.load()
>>> obj.hi()
'hi'
>>> obj.a
