I'm not sure if it makes sense to copy this test file yet; the majority of tests are failing or panicking and the underlying rust implementation is just using an external crate, not necessarily attempting to match CPython's behavior.

It probably makes sense to defer this PR for the reasons you mentioned above. Perhaps we could revisit this test suite in the future.

I agree adding many unittest.skiped tests doesn't give benefits as much as unittest.expectedFailure marked tests. But still it will show goals for newcomers.
