Changes (by SimonKing):

  * status:  needs_work => needs_review
  * work_issues:  Add examples; move code from ring.py to rings.py => Shall
                  one move code from ring.pyx to
                  rings.py?


Comment:

 I updated my patch, now as the background work in #9138 seems settled from
 my point of view.

 In that patch, I went for the "duplicate code for speed's sake" approach.
 I don't mind beig asked to change it, though (i.e., it seems possible to
 delete the ideal stuff from sage.rings.ring and move it over to
 sage.categories.rings).

 Depends on #10961 #9138 #11115
