Hi, two questions below seem to be orthogonal:

  Is #matr~ optimized by the compiler?

  Is not it desirable to implement ##matr as an (optimized) synonym for #matr~?

If the answer to the second question is positive, then one can maybe
improve things by returning a special value (such as -1) for scalars…

Thanks,
Ilya
