Because you have to instantiate the doggone thing for every integer type
where you might want to do Add.  And you have to anticipate which types
those are, or else do it when it's unnecessary.  It leads to a lot of
useless (unreadable) clutter in the code.  So nobody bothers with that;
we all just write X := X + 1, even when X is slightly complicated.
