N2930, Range-Based For Loop Wording (Without Concepts), provides begin() and end() non-member function templates for standard library types. It also provides general range access non-member templates: // 24.7 range access [iterator.range] template<typename C> auto begin(C& c) -> decltype(c.begin()); template<typename C> auto begin(const C& c) -> decltype(c.begin()); template<typename C> auto end(C& c) -> decltype(c.end()); template<typename C> auto end(const C& c) -> decltype(c.end()); template<typename T, size_t N> T* begin(T (&array)[N]); template<typename T, size_t N> T* end(T (&array)[N]); (Until the official WG21 site gets updated, you can see a copy of n2930 at http://mysite.verizon.net/beman/n2930.html) Should Boost.Range and/or RangeEx be modified and/or extended in light of N2930? Can Boost.Range, RangeEx, or some other Boost component help developers and users who want to take advantage of N2930 in C++03 now, and do so in a way that transitions smoothly to C++0x as language and library available? --Beman
