Slightly more than that: If you need to run cleanup code, whatever needs cleaned up should be a class and do the cleanup in the destructor. Take a file handle, for instance. Don't use open() or fopen() and then try to close it in a finally. Instead, use a file class and let it close itself by going out of scope.
