Summary -- Detect setting or deleting `__debug__`. Assigning to `__debug__` was a `SyntaxError` on the earliest version I tested (3.8). Deleting `__debug__` was made a `SyntaxError` in [BPO 45000], which said it was resolved in Python 3.10. However, `del __debug__` was also a runtime error (`NameError`) when I tested in Python 3.9.6, so I thought it was worth including 3.9 in this check. I don't think it was ever a *good* idea to try `del __debug__`, so I think there's also an argument for not making this version-dependent at all. That would only simplify the implementation very slightly, though. [BPO 45000]: https://github.com/python/cpython/issues/89163 Test Plan -- New inline tests. This also required adding a `PythonVersion` field to the `TestContext` that could be taken from the inline `ParseOptions` and making the version field on the options accessible.
