If we get null as $left & $right should we still run version comparison?

There was a problem hiding this comment.
Not really, but it wont hurt, since the types comparator will get type_null 2x and will return that types are comparable.
Adding extra condition just for nulles doesn't seem to bring any significant performance boost (was just testing this locally)
