Pickling array.array

For those interested in the same problem, the only solution I've found 
is to encapsulate the array instead of derive from it.  It sucks a bit, 
since all methods need to be implemented to redirect to array.array, but 
at least it's working.  I'm still wondering how to do it with derivation...

Thx and regards,

import array as arr
class array:
     def __init__(self, typecode, initializer=None):
         self.arr = arr.array(typecode, initializer)
     def __getstate__(self):
         return {'buffer': self.arr.tostring(),
                 'typecode': self.arr.typecode}
     def __setstate__(self, dict):
         self.arr = arr.array(dict['typecode'])
         self.arr.fromstring(dict['buffer'])
