Errata: Second only in monad support to Haskell and equivalently powerful languages e.g. OCaml and Scala, but much better than mainstream languages, I should've said. Also, I should have said that Rust helps with data races not races in general. Also, I should've said Rust's trait system was more practically powerful / usable that OCaml's first class modules and potentially more powerful overall but not quite there yet. This is what comes with writing enthusiastically, while suffering from a headache and brain fog. I swear I'm not an idiot and know my pure functional languages!
