- The parser no longer changes temporarily during parsing.
- Default values are not processed twice.
- Required mutually exclusive groups containing positional arguments are now supported.
- The missing arguments report now includes the names of all required optional and positional arguments.
- Unknown options can be intermixed with positional arguments in parse_known_intermixed_args().
- Issue: Rewrite parse_intermixed_args() in argparse #125355
* The parser is no longer temporary modified and can be used concurrently. * Default values are no long handled twice. * Report about missed arguments now contains names of all required optional and positional arguments. * Unknown options can be intermixed with positionals in parse_known_intermixed_args().

I think that was a bug. The result was different depending on the position of unknown option.

I do not understand this code. There were no tests, and the purpose is not clear to me. @hpaulj, @bitdancer, could you shed some light on this?
