#python peeps: If you assume, as I did, that #astral #ty's LSP JUST provides the type checking ty is known for, you'd be wrong :)
It's an all around IDE like LSP like pyright/basedpyright but is missing some of pyright's features like codelens, inlay hints and call/type hierarchies, in exchange for being much faster.
If you use both, don't be puzzled as I was when you hit your Goto Definition key mapping and get a list of 2 identical definitions.
Just pick one or the other and things will work how you expect.
I'm sticking with basedpyright for now but I'm putting myself on probation in that if I don't actually start using code lens and hint inlays I'll switch to ty for speed :)
