            The method can be used as a simple iterator computing and blocking
            the hitting sets on the fly. It essentially calls :func:`get`
            followed by :func:`block`. Each hitting set is reported as a list
            of objects in the original problem domain, i.e. it is mapped back
            from the solutions over Boolean variables computed by the
            underlying oracle.
