If you can test for "uncaught_exceptions" you can implement the

Sorry, years of python programming have made me shy of
destructors. It just looks a little less "magic" to me if I
specify the destruction explicitly after creating the object,
using the "scope(exit)" syntax. "scope(success)" and
"scope(failure)" have no analogy in destructors as far as I know.
Destructors just destroy the object, and doing more than that is
risking weird edge conditions.
But again, if you already have your elaborate destructor, you can
set "o.fail = true" in a "scope(failure)" statement, and the
destructor just has to check this.fail for how it's being
destroyed..
