Largely irrelevant here, but partial specialization of function templates
simply does not exist. We have been talking about adding an overload like:

 template<typename _Alloc>
   bool
   operator<(const vector<bool, _Alloc>&, const vector<bool, _Alloc>&)

or overloading std::lexicographical_compare, seems also an option.
