So ty is about 7x faster - but remember ty is still in development and may not catch the same errors / report false errors, so it's not a fair comparison yet.
Note that `uvx mypy` may give you inaccurate timings on macOS. The antivirus in macOS goes a little crazy the first time it executes a mypyc compiled program.
