Hello, internals!
I am wondering why don't we use ordinary `->` operator with safe null
handling? Programmers will be more prone to return null values. And thus,
in most of cases `?->` will replace `->`.
Why do we need another operator, if we can implement null safe in current
operator without BC breaks?
