You can do the same with std::type_info by supplying a template parameter other than the default std::less<>.  I understand this need, and I understand how simple it is when you truly are LessThanComparable (and lean that direction myself).  I just want to make sure that someone isn't going to argue that we should have followed the type_info design, since there's no true ordering for this type.
