Why can't const_begin be implemented as follows (for standard library
containers):

     template<typename Range>
     typename range_const_iterator<X>::type
     const_begin(Range& rng)
     {
         return begin(static_cast<const Range&>(rng));
     }

     template<typename Range>
     typename range_const_iterator<X>::type
     const_begin(const Range& rng)
     {
         return begin(rng);
     }

?
