Haxl is modern. Ponylang's concurrency is modern. Rust's concurrency is modern. lparallel and fset's affordances are not. I'm not sure why a single threaded regular expression compiler is mentioned here. I'd have to check. Is fset even using the current standard (not the newest stuff) for immutable-friendly data structures? Last time I checked they had used a lot of older stuff from Okasaki's work and much of that has been improved upon substantially now. Even Clojure is out of date, compared to this year's innovations!
