alt Hacker News> You are supposed to do as much programming as you can in the high level language, and only drop into the low level language as needed.
I think that's a neat idea, but in the reverse: do as much as you can in the lower level language, and only go up to the high level language when the convenience is worth the cost.
Roc allows this: every program has a platform written in a low-level language, and then the Roc program uses the API that the platform exposes.
Then how you want to balance high vs low is of course up to you :^)
roc lang looks very interesting, I see they use a lot of Zig and Rust, very unusual combo I think.
