Possibility to make an "option group" where the user has to use exactly one of the options in the group about commandline

Again @pheiberg thanks for posting the issue.

Issue contributes to make the library better (implying that issue will be fixed...) and so are always welcome.

This is issue was filed under enhancement, because this is a known behavior; also if not enough to describe your syntax.

Thanks for the reference, I'll read it. It' always good know what other do...

At glance
As a short reply (if my posts could be categorized this way...), I see in your last proposal a way of doing things perfectly aligned with the current philosophy.

A bit more in depth
Following the the idea to combining two behaviors, I'd say that a problem exists (to be honest). Since you can already combine it, an exception should be thrown to warn that X with Y should not be combined.

This is one of the key reason that have me brought to heavily refactoring the kernel and try to adhere some functional principles; but the second point is in its earliest stages. :))

Going ahead, I'm agree that such behaviour should be semantically supported by the parser (no exception -> we will be implemented).

Conclusion
Required will work as always, but when combined with MutuallyExclusiveSet it will be scoped to the matching set.

C/C: @nemec @mizipzor (main contrib. opinion appreciated)

I want to add one thing, since its an enhancement, fixing will be delayed until some refactorings occur in persing kernel.

Anyway we're a talking of very limited amount of time.

As you can see all enhancement are freezed during this time.

Metrics: we're taliking of days not months!!!

Considering the lack of activity, it's time to close this (just reopen if need be).
