The patch, under development on the sage-combinat patch server], creates the category GradedEnumeratedSets. It also:

It seems like it would be better to use degree as opposed to size for consistency with the "standard" graded things. Also, it seems like it might be better to have the degree method implemented on the parents. It could be somewhat confusing if the degree method on the elements corresponded to a different grading than the parent it belongs to.

Hi, here at SD35.5 I wanted to review #9280, but I see it depends on this ticket, which did not progress since 15 months. Is this ticket dead?

PS: moreover the patch url is dead...

We just discussed it with Vincent Delecroix, and where planning to finalize/review it during the Sage-Combinat days in Cernay (early February).

Should be fixed now.
