I think also out of the box standard library features. You can make production ready web apps. Also their initial approach to getting / sharing packages imho is useful.
So a decent package manager would do wonders. Rust has Cargo which does builds and packages. D has dub as well.
Definitely recommend making code sharing / reuse a breeze.
Thank you for working on this awesome project. One additional commentary I always make is that I wish Go and Rust had even a basic editor like the one Racket has: you can edit, and compile. You beat me to that suggestion so I'll keep an eye on your project.
Is there any possibility that you'll include some efforts towards doing back-end networking with this language as well? I could see multiplayer games needing servers after all.
