It's a breaking change, no question. And I don't know how much code
would be effected, but I imagine it to be pretty small, and in all
cases, the fix is to use mpl::tag instead of accessing ::tag directly.

Then again, maybe leave it alone, and eventually deprecate all of mpl
for something more modern? If we eventually migrate boost code away
from mpl, it seems we'll have to take breaking changes eventually.
