Ok, now I see what's going on.  Create a metafunction class
wrapper for the actual policy in the way you would create a functor
for a normal function.  It also makes sense why you might have
called it a metafunctor.  It's all starting to make sense. ;)  This is
also much less intrusive than what I was doing.
