Not really. Arrays should have been allowed to have discriminants. That was
missed in the language design. If they had discriminants you could write:
type Row is array (Positive range <>) of Float;
type Matrix (Width : Positive) is
array (Positive range <>) of Row (1..Width);
(Of course the array bounds should have been discriminants rather than
attributes)
