I see in a couple of bots this construction:
def main(*args): for arg in pywikibot.handleArgs(*args): etc.
Now, if I write instead of this def main(): for arg in pywikibot.handleArgs(): etc. the result seems to be just the same. I tried with valid global and with unique parameters as well. So, what is the difference? I know the theory that * means a variable width argument list, but if I omit it, the behaviour does not change.
