If there is a market for that, then I would build a new language from the ground up that is... better designed.

Brunost is just me throwing syntax at the wall to make a "nynorsk programming language". Less about careful design and more about getting something to work.

If I were to make a language intended for an important production system, it would be a compiled language that (probably) would go the Gleam route and compile to JS and some other language, while also being typesafe, having a package manager and so forth.
