Proposed resolution:

This wording is relative to N3485.

1. In [iterator.synopsis], header iterator synopsis, add the following declarations:

   namespace std {
     […]
     // 24.6.5, range access:
     template <class C> auto begin(C& c) -> decltype(c.begin());
     template <class C> auto begin(const C& c) -> decltype(c.begin());
     template <class C> auto end(C& c) -> decltype(c.end());
     template <class C> auto end(const C& c) -> decltype(c.end());
     template <class T, size_t N> T* begin(T (&array)[N]);
     template <class T, size_t N> T* end(T (&array)[N]);
     template <class C> auto cbegin(const C& c) -> decltype(std::begin(c));
     template <class C> auto cend(const C& c) -> decltype(std::end(c));
     template <class C> auto rbegin(C& c) -> decltype(c.rbegin());
     template <class C> auto rbegin(const C& c) -> decltype(c.rbegin());
     template <class C> auto rend(C& c) -> decltype(c.rend());
     template <class C> auto rend(const C& c) -> decltype(c.rend());
     template <class T, size_t N> reverse_iterator<T*> rbegin(T (&array)[N]);
     template <class T, size_t N> reverse_iterator<T*> rend(T (&array)[N]);
     template <class E> reverse_iterator<const E*> rbegin(initializer_list<E> il);
     template <class E> reverse_iterator<const E*> rend(initializer_list<E> il);
     template <class C> auto crbegin(const C& c) -> decltype(std::rbegin(c));
     template <class C> auto crend(const C& c) -> decltype(std::rend(c));
   }
   

2. At the end of [iterator.range], add:

   template <class C> auto cbegin(const C& c) -> decltype(std::begin(c));
   

   -?- Returns: std::begin(c).

   template <class C> auto cend(const C& c) -> decltype(std::end(c));
   

   -?- Returns: std::end(c).

   template <class C> auto rbegin(C& c) -> decltype(c.rbegin());
   template <class C> auto rbegin(const C& c) -> decltype(c.rbegin());
   

   -?- Returns: c.rbegin().

   template <class C> auto rend(C& c) -> decltype(c.rend());
   template <class C> auto rend(const C& c) -> decltype(c.rend());
   

   -?- Returns: c.rend().

   template <class T, size_t N> reverse_iterator<T*> rbegin(T (&array)[N]);
   

   -?- Returns: reverse_iterator<T*>(array + N).

   template <class T, size_t N> reverse_iterator<T*> rend(T (&array)[N]);
   

   -?- Returns: reverse_iterator<T*>(array).

   template <class E> reverse_iterator<const E*> rbegin(initializer_list<E> il);
   

   -?- Returns: reverse_iterator<const E*>(il.end()).

   template <class E> reverse_iterator<const E*> rend(initializer_list<E> il);
   

   -?- Returns: reverse_iterator<const E*>(il.begin()).

   template <class C> auto crbegin(const C& c) -> decltype(std::rbegin(c));
   

   -?- Returns: std::rbegin(c).

   template <class C> auto crend(const C& c) -> decltype(std::rend(c));
   

   -?- Returns: std::rend(c).
