Then what is the correct work-around to get past this "design"? Some
people, like me, make frequent use of boost::format (which your version
cannot replace because it does not implement 'g' formatting), and other
functions that output in characters specific to the locale and know
nothing about as::anything.

This is a problem. The library, perhaps rightly, doesn't follow
standard conventions but it also doesn't replicate those functions which
do. Can I use only your translation functionality without imbuing the
streams with your locale? Something tells me that won't work out quite

If this design is going to stick, then there certainly needs to be a
documented workaround so that those of us who need the behavior can get it.
