        It should be possible to throw the exception that a Failure
        represents into a generator.

        Within an exception handler, it should be possible to find the
        original Failure that caused the current exception (if it was

        When a Failure is constructed in the context of an exception
        handler that is handling an exception raised by
        throwExceptionIntoGenerator, the new Failure should be chained to that
        original Failure.
