How to use the cloudpickle.CloudPickler.save function in cloudpickle

#print 'saving...', len(self.traceStack), obj, type(obj)

        if id(obj) in self.memo: #deal with this better!!!
            CloudPickler.save(self,obj)

            if id(obj) not in self.memo:  #forcibly memoize objects for debug printing..
                self.memoize(obj)
