Feature request: Static type checking with mypy

[mwip]

I love the work that is done with ruff. Its capabilities and speed help me improve my, and I'm sure other's, code quality significantly. Currently, I am also using mypy for static type checking during development, which has a similar effect on improving code quality.

For now, I was only able to combine ruff and mypy with a python-lsp-server setup. Are there any plans to integrate static type checking in ruff-lsp?

You can use pyright - in my experience it does a better job than mypy at type-checking, does not require python to work (which means you won't face any issues like conflicting dependencies between your project and mypy) and provides its own LSP server.
