Ditto here - mainly using generics. This also gives you the opportunity of
defining exactly what exception you want raised if you accidentally overstray
the bounds of the input type.
Hands up all those who have never done i++ and had the result go over the
intended maximum value of i? Ada won't stop you doing this (ie committing a
bug) - but will tell you about it at run-time, and allow you to write code that
will work regardless.
