OrderedDict的JsonPickle子类不工作

Question

我做错了什么：

class A(collections.OrderedDict):
    def __init__(self,*largs,**kwargs):
        super(A,self).__init__(*largs,**kwargs);
    def __reduce__(self):
        return super(A,self).__reduce__()

dt = collections.OrderedDict([(1,3),(34,2)]) # pickles fine
d=A([(1,3),(34,2)])                          # pickles fine

js=pickle.dumps([d,dt])
print(js)
temp = pickle.loads(js)
print(temp)

# but it does not jsonpickle.decode ????
js=jsonpickle.encode(d)
print(js)
temp = jsonpickle.decode(js)
print(temp)
