PyCXX question on __module__ attribute

[kishor s. <kis...@gm...>]

Hi CXX Users,

I am using PyCXX to write extension classes. I am trying to pickle the
extension object using cPickle. cPickle break as __module__ attribute is
not on the objects
e.g.

In [1]: import example
range object created 0x196b290
range object destroyed 0x196b290

In [2]: example.range.__name__
Out[2]: 'range'

In [3]: example.range.__doc__
Out[3]: 'range(start,stop,stride)'

*In [4]: example.range.__module__*

*In [5]: example.range.__module__ is None*
*Out[5]: True*

I tried debugging the code it seems to be passing correct module name to
Py_InitModule4 function but it is not reflected in the python.

Any help/pointers on how to fix?

Thanks,
Kishor Sharma
