import optparse

def _(s): return s

class OptionParser(optparse.OptionParser):
    def _match_long_opt(self, opt):
        if opt in self._long_opt:
            return opt
        raise optparse.BadOptionError(_("no such option: %s") % opt)

    p = OptionParser()
    p.add_option("--long", action="store_true")
    options, args = p.parse_args()
    print "long:", options.long
