Recently I was surprised that there is module which provides autocomplete for options[1]. It was a pity to see that it uses optparse and it is not clear when it will be available for argparse. As you know optparse module is old and will be deprecated. However, autocomplete is a very useful feature. As I've understood we can provide similar possibility for argparse[2]. Is it a good idea? At this time it only a plan, nothing more, so it can be not implemented due to lack of time. However, can we implement this feature in the future?
