This isn't either-or. Sure, if there's a partial fix that's a step
towards The Right Answer, then that's better than a partial fix that
isn't. I'm not arguing for doing the wrong thing for the sake of doing
the wrong thing! But, we shouldn't be resisting papering-over on
principle; sometimes it's the best way to deliver a better compiler with
the resources we have available.
