I don't see what's new about that.

It seems that the person who feels most uneasy about it is yourself
because it doesn't work like you want it to.

It would almost certainly be shorter and easier to understand,
especially since you are *also* handling sys.argv directly in your code
to prevent argparse to work as designed.

But since you are probably the only person who will have to read your
code in the future that's not our problem.
