If we're not looking to use all the other null-coalescing variants (?=, ?(), ...) - which is something I'm pleased about, as I do think that scattering that many ?'s about is likely to lead to ugly code - then it would probably be fine to just use ? for this operation, so we'd have foo?bar?baz rather than needing foo?.bar?.baz.
