Actually, it's dealing with SmallInt (or ShortInt). And if the 
programmer does not know that, then it might be an issue...

Imagine the generic code (something more complex than "Add") would 
somehow do something that differs for SmallInt and Integer. Like using 

Sure it can be solved by explicit specialization "Add<Integer>(1,1)".
But to solve it that way, the programmer needs to know... And he might
