Thanks for the rewrite! This is a great expansion. Unfortunately I didn’t have the time to review it before the merge. If I find something to be improved I will let you know.

Are you sure? Yet in your 2003 blog post [*Python main() functions*](https://www.artima.com/weblogs/viewpost.jsp?thread=4829) you promoted the opposite idiom `if __name__ == "__main__": sys.exit(main())` over the idiom `if __name__ == "__main__": main()`:

> Now the `sys.exit()` calls are annoying: when `main()` calls `sys.exit()`, your interactive Python interpreter will exit! The remedy is to let `main()`'s return value specify the exit status.

I am interested in the rationale if you changed your mind.
