Very exciting stuff! I submitted a link to the actual MR when this happened; wasn’t discussed much at the time: https://news.ycombinator.com/item?id=37932016 https://news.ycombinator.com/item?id=37932016 (This current submission is really nice; you get to hear more from Matthew about what’s going on.) Chez Scheme (pronounced “shay-scheme”) is the most performant and compliant Scheme implementation out there. [1] For a long time it was closed-source, but was recently open-sourced. It now forms the foundation of the Racket language. (So, I guess that means HN relies on it, provided Arc is using a recent version of Racket.) I asked Matthew why he picked Chez to base Racket off of, and I want to say that he picked it because it implemented continuations really really well and had a good garbage collector too. I could be wrong. [1]: https://ecraven.github.io/r7rs-benchmarks/ https://ecraven.github.io/r7rs-benchmarks/
