It champions #TonyHoare's #CSP model of concurrency which takes me back. Back to the time I failed to get funding for a start-up to build an #Occam compiler targeting i386. Which was largely a ploy to get the UK government to buy me some neat kit 🤷♂️
I've put together a little library that tries to focus the user on developing parallel applications in #OCaml - it's still an experimental project but we've started with a few real applications. It's available here: https://github.com/roburio/miou. The library is very straightforward about what you can do with OCaml 5 and #parallelism. At the very least, it may look rudimentary but it leaves plenty of room for the user to do what they want to do - while imposing some good practices.
