The csv module (and the _csv module which underpins it) should work with
2.2.3.  If they don't, please file a bug report.

That was the intention with the csv module.  I wonder if some limitations to
use of sets with 2.2.x could be gotten around by adding a __future__ import?
Maybe itertools is also needed.

Yes, that's a worthwhile goal.
