I think you're referring to OxCaml. I'd love to see this make a huge splash. Right now one of the biggest shortcomings of OCaml, is one is still stuck implementing so much stuff from scratch. Languages like Rust, Go and Java have HUGE ecosystems. OCaml is just as old (even older than Rust since OCaml inspired Rust and its original compiler was written in OCaml) as these languages. Since it's not been as popular, it's hard to find well-supported libraries.
I too wish that some OxCaml features bring new blood to OCaml. I've been using OCaml for a few years for personal projects and I find the language really simple and powerful at the same time, but I had to implement me some foundational libraries (e.g. proper JSON, parser combinators), and now I'm considering porting one of those projects to Rust just so I can have unboxed types and better Windows support.
> even older than Rust
That's an understatement, (O)Caml is between 17 and 25 years older than Rust 0.1 depending on which Caml implementation you start counting from.
