Hi, thank you all for your explanations.
I still wonder why a concept like "references" was not implemented in Python. I think it is (even if small) an overhead to wrap an object in a list or a dictionary. Isn't it possible to extend Python in a way to use real references? Or isn't that regarded as necessary? Thanks for any hints, Torsten. -- http://mail.python.org/mailman/listinfo/python-list
