    With some restrictions it can be done.
    For example:
            template<int A11, int A12, int A13>, //As far as I know we can
emit the typename name, don't we?
            template<int A21, int A22, int A23>,
            template<int A31, int A32, int A33>,
    class compile_time_matrix;
    for compile_time_matrix we can do that. But is what really what you

    Actually the purpose of the library is to choose best algorithm at
compile-time, and then apply
    it at run-time.
