There's no such thing as LangAS::Generic, there's LangAS::Default. Default
doesn't have to map to something that's actually useful, and it actually does
not. There's no actual mechanism to get a flat pointer. And I have no idea what
notion spreading you are talking about - this merely maintains the status quo,
wherein everybody grabs an AS 0 pointer and hopes for the best. So I have no
idea what you are talking about, if I'm honest.
