That's true, that's why they are detected sooner, when it is
less costly to fix them.
It would be even less costly if they weren't possible.
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.
