But similar constructions in other languages (Python's with- statement, various Lisp versions, using in C#) can handle this cleanly. C++ doesn't give you "finally" and since you can't do non-trivial cleanup in destructors RAII is really a lot less useful than it seems at first blush.

In C++ you can write the cleanup code once in the destructor, "similar constructions in other languages" must be written every time you use it. You can and should do "non-trivial cleanup in destructors", e.g. DB rollback, but you should do only cleanup in destructors.
