Given the following: template <typename T, std::size_t D1> void foo(T (&arr)[D1]) { typedef boost::multi_array_ref < typename boost::remove_all_extents<T>::type, boost::rank<T[D1]>::value

arr_type;

// ? = ExtentList or extents_tuple. arr_type ma(arr, ?); } Are there any existing tools to create an ExtentList or extents_tuple obj from the type of arr? Thanks, Mostafa
