In all seriousness, though, I really feel like that would be the ultimate bug magnet, since it'd be easy to forget to un-wrap the object afterwards.

I find the '?.' syntax very ugly, much more so in the examples of chained attributes.

A much better way to handle the use case is to wrap objects in a class that gives this "propagating None" behavior with plain attribute access. A nice implementation was presented in this thread.

I think that if there's "strong hesitation" about something being "too
ugly" it can't really be described as "the perfect syntax". IIRC there
were a couple alternatives being discussed that would have reduced the
number of question marks to one [or one per object which might be None].
