[Python-ideas] Null coalescing operator

[David Mertz]

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.
