Because people are continuing this discussion, I'll say again that
argparse already supports this:

>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('-v', '--verbose', action='store_true')
>>> parser.parse_args(['-v'])

If you want to also have a -V/--version argument, you can do that too:

>>> parser.add_argument('-V', '--version', action='version', version='3.5')
>>> parser.parse_args(['-V'])

And now back to our regularly scheduled discussion of actual PEP issues. ;-)

Where did you get that preposterous hypothesis?
Did Steve tell you that?
