The Flix Programming Language

Don't know if I posted this one before, but this language is interesting (to me). I like the internalized support for Datalog, and the explicit handling of effects.
Especially interesting is that they have go-like coroutines and channels implemented on Project Loom's virtual threads (https://nitter.fly.dev/flixlang/status/1572480682886062080#m) in Java 19 and up. Virtual threads are extremely lightweight to the point that you can create millions of them in one program and the per-thread overhead is minimal (unlike system-level threads).
If you're not familiar with Datalog, this blog series looks like a pretty good primer.
