Does deepcopy work properly with Cython?

[Kyungwon Chun]

Does deepcopy work properly with Cython? I got False from 'B(A(1)).a.v
== 1' with the following code.

from copy import deepcopy

cdef class A(object):
cdef public double v
def __init__(self, double v):
self.v = v

cdef class B(object):
cdef public A a
def __init__(self, A a):
self.a = deepcopy(a)

No. In this case (you are using extension types, i.e cdef classes) you
have to implement the pickle protocol for your class

I got the point.
Thanks, Lisandro.
