[boost] [type_traits] request for decayed<T>::type

Hi,

The following trait is supposed to make it easier to forward
arguments in generic code and in particular string literals. For example, I 
will use it when I update boost.assign
to use const T& arguments instead of T arguments. It could also be used to
make a better version of std::make_pair():

  template< class F, class S >
    inline std::pair< typename decayed<F>::type,
                      typename decayed<S>::type >
    make_pair( const F& f, const S& s )
    {
        return std::pair< typename decayed<F>::type,
                          typename decayed<S>::type >( f, s );
    }

Any thoughts from the type_traits authors?
Do anybody mind if I add this to the cvs and make some docs for the
type-traits library?
