        # we could throw exceptions of various types, but why - does it really
        # add anything? possibly some slightly better user feedback potential.
        # however, this can be written by hand by performing individual checks
        # ala the code in verify_iban() itself where required, which is likely
        # almost never. for the increased complexity and
        # maintenance/documentation cost, i say, therefore: no. no exceptions.
