[New-bugs-announce] [issue29937] argparse mutex group should allow mandatory parameters

[Mark Nolan]

New submission from Mark Nolan:

I see elsewhere, and from use, that a mutex group will not support mandatory positional parameters.

TBH, I don't understand why this should be any different from any other option, but if it must, then I think it should follow the 'required' parameter of the mutex.

So, it should be possible to have a mutex group where one option must be chosen and that option must have positional parameters.

(My first post here. Not sure of any other way to discuss with the argparse development group. Point me somewhere else if appropriate).
