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.

IIRC, one of the reasons for "breaking out"[1] the standard library (and its test suite) was to allow for things like this.
