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.
