It's not like we get away with it in Java. In the bank I work with, we index arrays above the integer limit less than we calculate increasing prices times quantity, and I have memories of stupid overflows turning to negative. Especially since we used fixed point integer to represent decimal numbers... We have entire special libraries for these and we still fail sometimes. Reminds me I have to reconcile a total price mismatch between a C# interface and a Java backend on monday...
