TypeError: store_json() missing 3 required positional arguments: 'opt_str', 'value', and 'parser'

i use this version in product env, so i have no update raven to see if this bud have fix. i read source code, it is because store_json need (option, opt_str, value, parser) but

class StoreJsonAction(argparse.Action):
    def __call__(self, parser, namespace, values, option_string=None):
        setattr(namespace, self.dest, store_json(values[0]))

if alread fix, sorry to bother.

@Petelin thx for reporting the issue. careful with the "{'as':1}", as it is not valid JSON.
