Where I work, we use many different languages. Heck, today I am looking at some Jovial (!) code. Usually, when I am "stuck" with just C++, I've implemented classes that behave more like Ada. Years ago, I wrote a class that does rendezvouses. A couple of years ago, a wrote a class template that would do range/overflow checking. That, of course, is trivial. The neat thing about it is that it used template specialization to remove unnecessary checks at compile-time (e.g., the compiler could determine that the arithmetic operation could not overflow). It would "track" a variable's max. possible bounds as it was manipulated, and strip the unnecessary checks from expressions (again, all at compile-time). I published an article on it in Dr. Dobb's.
