That's a good way of checking for a non-zero exit value (as is done in type-checker-errors.s), but XFAIL has the advantage of marking a test as something that _should_ work, and having it show up in the test stats as such.

Happy to drop this file and just try to land type-checker-errors.s if that's preferred?
