@jwakely Does this require an LWG issue?

If this is the LWG, there is no way to implement a functional cartesian_view according to the draft until the LWG makes any decisions.

That may well be so, but is not an editorial concern.

vector also wasn't implementable until C++23, but that also didn't get fixed editorially.

That's fine. This is not a final standard, there is no great urgency to fix defects in a draft.

Implementors can easily do this without waiting for an LWG decision. It's common that we implement fixes before they make it into the draft.

Although the changes here seem correct, I don't think it's editorial. Please submit an LWG issue instead, thanks!

Could you kindly edit the pull request to avoid sounding disparaging of the existing work and the people who have contributed it?

@tkoeppe Sorry for the misunderstanding caused by the misuse of words, I will be more careful with words in the future pull.

@jwakely, thanks for the suggestion.
The reason I insist this is an editorial fix is that it was clearly an oversight, and I believe the fix was what the author originally intended. Maybe we can ask the author again about this opinion after he finishes the vacation.

If this is definitely an LWG, I'd like to ask when it would be appropriate to submit it to the LWG, as the C++23 draft hasn't been published yet.

Much appreciated!

The paper doesn't ultimately "belong" to the author, so even if an author later changes their mind or clarifies something, that cannot just "bypass" the committee approval. So the normal thing to do in that case is to record the desired correction in an LWG issue. Usually those kinds of issues can be processed very fast. In any case the final standard won't be released for many months, and the committee can always approve issues. So there's plenty of time.

It's perfectly normal for large papers to contain errors and have those fixed later on.

Specifically addressing your question, you should submit an issue to lwgchair now, so that the matter does not get lost.

Closed and intends to submit LWG for this.
