I'm aware of the ongoing work to enable multicore parallelism in OCaml. It's the reason why I mentioned OCaml in my comment. My comment was rhetoric. My apologies if it was not clear.

That said, I don't see the link between the work done on OCaml multicore parallelism and Go "being too opinionated"...

If I follow you, Go people, unlike OCaml people, are "too opinionated", and don't "carefully investigate existing code" and don't "elaborate modern and efficient code". Do you realize how arrogant (and a bit ridiculous) this sounds?
