If it won't take a long time, is it possible to rewrite the above code snnipet making use of boost.Ref?

#include #include #include <cassert> int main() { typedef boost::reference_wrapper<double> double_ref_t; boost::array array; double_ref_t d0( array[0] ); double_ref_t d1( array[1] ); array[0] = 1.0; array[1] = 2.0; assert( d1 == 2.0 ); d0 += d1; assert( d0 == 3.0 ); }
