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/BRTRKGY6RLTHZJQ2US4LO7DYLSGXQ5GM/ Best regards, Piotr On Thu, Sep 15, 2022 at 6:54 PM Maarten Nieber <mnie...@gmail.com> wrote: > Hi Piotr, > > doesn't Doug's reply of 8:03 address this point?
