Hi Maarten, I'm sorry for the confusion - it was bad wording on my part. What I really meant was that the problem with the None-aware operator, and the reason why PEP505 has not been accepted for such a long time, is that there's no consensus regarding the need for it (and not necessarily the problem with the operator used to represent it - although this topic has also been raised). Take a look at the response by Steve Dower: https://mail.python.org/archives/list/python-dev@python.org/message/BRTRKGY6...

Hi Piotr,
doesn't Doug's reply of 8:03 address this point? As he says, the none-aware operator never gives you None when you ask for a missing attribute (these cases always raise an exception). If we look at these two alternatives
phone1 = book.publisher?.owner.phone phone2 = book.publisher.owner.phone if book.publisher else None
then they behave exactly the same. If we would misspell "owner" then in both versions we'd get the same AttributeError under the same conditions.
