Yes, slices in Ada are the solution for one-dimensional data, which is 
by far the most common case.  However, PL/I allowed multidimensional 
slicing, and it is the one PL/I feature that I miss in Ada.  Of course, 
not many people program matrix multiplication and inversion in a way 
that requires multidimensional slicing. ;-)
