We just posted the thrilling conclusion to our blog trilogy on Oxidizing OCaml, which talks about some of the things we’ve been working on (and some of our space-age plans) around extending OCaml to support some of the same kinds of things that Rust lets you do, but in a distinctly OCaml-ish way. Here are the posts: - [Locality](https://blog.janestreet.com/oxidizing-ocaml-locality/) - [Rust Style Ownership](https://blog.janestreet.com/oxidizing-ocaml-ownership/) - [Data Race Freedom](https://blog.janestreet.com/oxidizing-ocaml-parallelism/) Maybe more excitingly, you can play around with the version of our internal compiler that has the bits of this we’ve implemented thus far (mostly, the local/global stuff, but the beginnings of uniqueness as well) as well as our open-source libraries, via an [opam switch](https://github.com/janestreet/opam-repository/tree/with-extensions). This is very much a bleeding-edge, unstable version. We use it internally for real work, but we refactor it mercilessly, and the language features are most definitely not stable. We hope one day to propose a lot of this upstream, but for now, it’s just a preview of some interesting experiments. The thing I’m most excited about all of this is the prospect of data-race free OCaml. The ability to leverage the great work done by the Multicore team, but safely, is a prospect I’m very much looking forward to. Also, a bunch of Jane Street compiler folk will be at ICFP next week. If you’re interested in learning more, that’s a good time to grab one of us. y --- _[View the full topic](https://discuss.ocaml.org/t/oxidizing-ocaml-and-a-new-opam-switch/12942)._
