Kind of looks like an alternative universe where Rust really leaned into its initial Ruby influences. IMO the most interesting thing was kicked down the road, I'd like to see more of the plan for concurrency. Go's concurrency (which it says they're thinking of) kind of sucks for lots of things, like "do these tasks in parallel and give me the return values". Go can do it with channels and all that, but Rayon's par_iter() just magically makes it all work nicely.
