Thank you for all those interesting news! Pretty excited to see that land in the compiler!
It seems like you look to be interested in “backend stuff” (e.g. with will to communicate with SQL with a dense binary format). So is the implicit meaning of your post that Elm is moving to something more “fullstack”?
Also I noticed you move the target language from JS to C (with the BIGNUM part). Do you plan using some Elm → C → WASM pipeline?
