How expensive is integer-overflow trapping in C++?

Perhaps we can have both. E.g.

    __checked__ int a;           // aborts on overflow
    __throwing_checked__ int b;  // throws exception on overflow

You could have the same syntax for unsigned ints.

D has checkedint which does this cleanly in a template
