As I remember the discussion, I thought he'd more or less conceded on
the use of ? but there was disagreement on how to implement it that
never got resolved. Concerns like, you can't have a?.b return None
because then a?.b() isn't callable, unless you want to use a?.b?() for
this case, or some people wanted to have "a?" [where a is None] return a
magic object whose attribute/call/getitem would give no error, but that
would have to keep returning itself and never actually return None for
chained operators.
