Ante is still mostly unusable unfortunately! Ownership & Borrowing were a relatively recent change and I've still yet to implement them. Algebraic effects are also still in progress in a dev branch and won't be merged for some time. You can use the language today but it will feel more like C with traits, generics, and bugs rather than a more featureful language.

The language does have a basic language server already though! It currently supports inline diagnostics and hover to show type.
