We could actually define ?? as a binary
I was thinking about the case where you use a module, only to define a
class that you then instantiate like this:
use Some::Module::That::Defines::A::Class;
our Some::Module::That::Defines::A::Class $foo := new;
and I keep thinking that that's too redundant. It's not so much that
