It would be very nice if these complex corner cases had a set of test cases which could be run by all implementations (CPython, Jython, IronPython, PyPy, etc). I don't know. Maybe the CPython test suite serves that purpose, but it seems like it would be helpful if this sort of "validation suite" was maintained as a separate project all implementations could use and contribute to.

We are going to start contributing tests back real soon now. I'm not sure that these are the best tests to contribute as they require a version of Python to compare against rather than being nice and stand alone. But I'm sure we have other tests which cover this as well just not as exhaustively.
We could also possibly check in the baseline file and then CPython could compare it's self to previous versions but it'd probably be a pretty big file - so it probably shouldn't be included in the standard install in the tests directory.
