Traceback (most recent call last):
   File "gummy.py", line 12, in <module>
     GummyConsumer.run()
   File "plumbum/cli/application.py", line 480, in run
     ordered, tailargs = inst._validate_args(swfuncs, tailargs)
   File "plumbum/cli/application.py", line 431, in _validate_args
     positional[args_names.index(item)] = m.annotations[item]
 ValueError: 'return' is not in list

This traceback is triggered if main() of cli.Application has a typed return i.e.:

 class GummyConsumer(cli.Application):
     def main(self, bear: GummyBear) -> None:
         print('MUNCH MUNCH MUNCH')

This should be sorted out somehow for #334 for full typing information. Forked this from #336 to be more precise.
