Shure it is usefull, very usefull indeed. Only you started off wrong:

namespace Ada
    {
    template <
        class Base_Type,
        Base_Type The_First,
        Base_Type The_Last>
    class Range
        {
        .....
        }

    template <
        class Element_Type,
        class Index_Type>  // derived from Range.
    class Array
        {
        .....
        }
    }
