Changes (by SimonKing):
* status: needs_review => needs_work
* work_issues: => comparison of BooleanPolynomialRings; one doctest fix
Comment:
Actually the comparison code should be completely removed: Boolean
polynomial rings are unique parents, and thus they are equal if and only
if they are identical.
So, I will submit a new patch, that removes both _cmp_ and `__richcmp__`
completely (but perhaps moving the old tests to a new place) and fixes the
doc test error that occurs in combination with #11342.
