* Use Boost style naming conventions (i.e. safe_int, not SafeInt).
* Don't use exception specifications.
* Use functions instead of macros.
* use std::numeric_limits<T>::min/max() instead of computing it for
* long long is not portable
* It's better to use non-members for operator+, operator-, etc.
  It's odd that you overload for SafeInt<T>() + S, but not S + SafeInt<T>().
