OK, I think I understand.  If the goal is to allow unsigned arithmetic 
with automatic overflow detection, they we'd have to add unsigned 
integer primitives to the language.

If the goal is only to provide automatic overflow detection for the 
existing types however, I don't think that any additional unsigned types 
would be required.
