Astral – "We're building a new static type checker for Python"
No named tuple support is a deal-breaker for some projects. This is directly from their GitHub issues comments[1]:
> Duplicate of #5613, still low priority, better use dataclasses, as suggested above.

Python 3.13.0 Is Released
disclaimer: I don't work on big codebases.
Pylance with pyright[0] while developing (with strict mode) and mypy[1] with pre-commit and CI.
Previously, I had to rely on pyright in pre-commit and CI for a while because mypy didn’t support PEP 695 until its 1.11 release in July.

Free-threaded CPython is ready to experiment with
https://github.com/python/mypy
> Python itself doesn't do that
The type syntax is python. MyPy is part of Python. It's maintained by the python foundation. Mypy is not part of CPython because modularity is good, the same way that ANSI C doesn't compile anything, that's what gcc, clang, etc are for.
Mojo is literally exactly the same way, the types are optional, and the tooling handles type checking and compilation.
