    Description

      In order to save an ObjectId to disk or to pass it between processes it is best if it can be pickled. (Having to insert code all over the place to turn it into a string and back into ObjectId is a pain.)

      >>> pickle.dumps(bson.ObjectId("112233445566"))
      TypeError: a class that defines _slots_ without defining _getstate_ cannot be pickled
