It's not clear what you expected the behaviour to be. A function cannot both raise an exception and return a value. In any case, you are correct in saying "the next option, '-d', is taken as the argument." I do not think this is a bug. See <http://pubs.opengroup.org/onlinepubs/9699919799/functions/getopt.html> for the Posix specification of "getopt". Perhaps you are confused by a bug or quirk of "argparse", where it treats most CLI arguments that begin with a dash specially, even if according to Posix they would be associated with an option. See Issue 9334.
