7652	compile-time checked access	Tobias Loew	Marshall Clow	"Since code like

boost::array<int,2> test;
test[2] = 1;
test[-1] = 1;

compiles correctly on some compilers (even without warnings). I suggest adding compile checked functions for static access to arrays like:
        template<size_type i>
        reference at() 
        { 
            BOOST_STATIC_ASSERT( (i < N) );
            return elems[i]; 
        }

        template<size_type i>
        const_reference at() const
        { 
            BOOST_STATIC_ASSERT( (i < N) );
            return elems[i]; 
        }


then code like:

boost::array<int,2> test;
test.at<2> = 1;
test.at<-1> = 1;

would result in the expected errors."	Feature Requests	assigned	Boost 1.54.0	array	Boost 1.52.0	Optimization
