[Boost-users] [array] range check (at compile time)

Hi, Lately I find myself using boost::array intesively, specially in small demo programs. Sometimes, when "manually" accessing the elements I type a index out of range. The library can detect these errors once the program is running but I found this a waste, also I was surprised not to see this kind of static check not implemented in the library. So I wanted to see if I could enforce range checking at compile time, and I come out with this solution. namespace boost{ //sorry about the namespace name template const T& get(boost::array const& arr){ BOOST_STATIC_ASSERT(IDX T& get(boost::array& arr){ BOOST_STATIC_ASSERT(IDX a = {1,2,3}; std::clog<(a)<(a)<
