I see - however, this requires the declaration of a constrained
subtype.
What about this:

procedure P (X : in String; Y : in String);

This procedure accepts two strings of any length - and they can have
different lengths. What about limiting this and allowing the user to
call P only with two strings of the same length?
Declaring a constrained subtype would fix the length to the one used
in type declaration. Is it possible to define P in a way that allows
strings of any length, but equal?
