 * work_issues:  How to store domain and codomain? =>


Comment:

 Since the patches have bit-rotted for so long, I guess it makes sense to
 start from scratch. Most part of the discussion here was about different
 ways to store the _domain and _codomain. Since it should now be possible
 to have fast ring-behaviour defined via category framework, I suppose one
 can simply make them cdef attributes, which should be the fastest
 solution.
