The problem with doing that is that it's ambiguous. There's no way of telling which attribute is allowed to coalesce.
You could of course support exactly the same syntax being proposed as a language change, e.g. from operator import attrgetter r = attrgetter('b?.x?.z') and then you wouldn't even need the `coalesce` argument. Cheers, -Barry
