As far as I am concerned, boost::type_info::name *must*
return the same value as std::type_info::name. You have
to expect that use of boost::type_info will be mixed
with std::type_info. It's unreasonable to expect everything
to use boost::type_info, and if the behavior is different,
it *will* cause surprises. You could perhaps make a case
for different behavior if boost::type_info were completely
separate, but since boost::type_info inherits from std::type_info,
there's absolutely no excuse.
