Just noting a couple recent discussions (the first has a number of links to other discussions near the top of the thread):
- Introducing a Safe Navigation Operator in Python
- Safe navigation operators by way of expression result queries
For myself, I’m fairly neutral on it. I am quite sure I would use it, if added, but it’s unclear how much and if the other impacts on the language would be justified by the utility, so I tend to stay out of these discussions.
