That's great news! TIL that ty is also a language server, which means it replaces not only mypy, but also Pyright in Neovim/VSCode.

Having fast and reliable code indexing, enable good "go to definition", completion and auto import is actually very exciting.

Pyright/pylance were a boon because they were the first non-pycharm good implementation.

But they still have rough edges and will fail from time to time, not to mention the latency.
