For completeness, I have (finally) looked in the archives for previous
proposals for the same feature. It used to be called "safe dereference"
or "safe arrow", and was discussed over a decade ago.
Here are the three threads I found:

It would be worth reading them, in case some of things discussed then
were not discussed this time around. And maybe a ten years old patch can
still be somewhat useful.
