Is vars() the most useless Python built-in ever?

Dear Peter, and Steven, thanks again for engaging with my script. I'm

This... is true. I could have sworn that's not the way argparse behaved
when I wrote that snippet, but I've been very wrong before about similar
things. Anyway my main() function looks much better now :)

I blush to confess I would first need to write a test suite. But yeah,
will do both, thanks for the recommendation.

Cheers,
