This is fixed by #12950. There is a doctest on line 2429 of sage/symbolic/expression.pyx
. We should close this ticket when that is merged.

Patch is at #12950, but still a valid ticket; that was a meta-ticket for the Pynac upgrade.

Same question as #1861: why doesn't this count as duplicate/invalid/wontfix?
In my opinion (only?), tickets that are closed by metatickets are not duplicates. It seems better to me (only?) to make it clear that work went into all of the issues we close, instead of making it seem like we have hundreds of duplicates that people open. We already do have enough duplicates as it is :)
And we certainly fixed it, so it's not "wontfix", and it's not invalid either, or at least wasn't before #12950, which however, explicitly refers to this ticket - it's not like some other change in #12950 made this invalid, which does sometimes happen.

If the issue is fixed by a different ticket, then this ticket should be either a "duplicate" or a "worksforme".
Has a doctest been added for this? If not, one could consider needs_work.

I simply disagree. So you are saying that, hypothetically, a gigantic metaticket for foo.spkg that bundles fifty changes, all of which are doctested by some huge patch at that ticket, means all the others are duplicates? That seems to denigrate the hard work that went into each of those other tickets. Although the people currently working on these particular tickets are not counting on this material for promotion, that is certainly a future possibility, as standards evolve, especially at less research-focused institutions.

Yes, it is at #12950.

You could give credit to those people on the other gigantic metaticket.
On this particular ticket here, I don't see any work done, so I would simply close it as duplicate.

Which Burcin did. The point was that although a ticket isn't a great measure of work, we don't have to make it an even worse measure.

Well, I was going by the fact that someone else filled in author and reviewer fields and the work "just happened" to be there; see also the discussion at #12950. But if you insist, I suppose I've engaged in enough bikeshedding for one day.

- Resolution set to duplicate
- Status changed from positive_review to closed
Likely the solution will be related with #11506.
