Even if it were made to work, though, it'd mean you suddenly and
unexpectedly get backward-incompatible changes when you run your code
on a new version. Effectively, that directive would say "hey, you know
that __future__ feature, well, I'd rather just not bother - get the
breakage right away". Kinda defeats the purpose :)
