## Summary Restructures and cleans up the `typing.Final` test suite. Also adds a few more tests with TODOs based on the [typing spec for `typing.Final`](https://typing.python.org/en/latest/spec/qualifiers.html#uppercase-final).
Markdown files within the mdtest/ subdirectory are tests of type inference and type checking;
executed by the tests/mdtest.rs integration test.
See crates/ty_test/README.md for documentation of this test format.
