C# has the checked and unchecked operators 
(http://msdn.microsoft.com/en-us/library/khy08726.aspx), which 
allow the programmer to specify if overflows should wrap of fail 
within an arithmetic expression. That could be a useful addition 
to D.

However, a language that doesn't have unsigned integers and 
modular arithmetic is IMHO not a system language, because that is 
how most hardware works internally.
