Comment 15 for bug 1268439

In the case of cinder (and I guess other projects too, but I only really follow cinder) we keep adding more and more ugly python 3 compatibility fixes, but we still can't actually run on python 3, so all we've gained is ugly code. We discussed at the mid-cycle meetup forcing the python3 work out-of-tree until it actually works and has CI, then fixing up the main tree in a clean series of patches derived from that tree. I'll put something on the -dev mailing list...
