Description (last modified by chapoton)

In Sage 4.1, the category of a category was changed from Objects() to Sets(). I.e. we used to have:

sage: Groups().category()
Category of objects

And now we have:

sage: Groups().category()
Category of sets

The attached patch reverts this, in particular because the objects of Sets() are exactly the parents.

For the record, all tests pass with this applied.

  • Reviewers set to Mike Hansen
  • Status changed from needs_review to positive_review

I think this can go in now and then we'll switch it over to the "Category of Categories" when appropriate.
