alt Hacker NewsThis language has been something I've wanted to build for years. For a while I thought I'd get my PhD and build it there. But now it's very possible to have Claude build it while I'm at work and give it intense code review every day. It's still not in a "useful" place yet, but I'm curious what fellow programmers think of a language like this. If I continue work is this something anyone thinks they'd enjoy using? Would love some feedback, thanks!

It's a really great concept. What guarantees are made by the prover?
Success in programming languages is not simply if-you-build-it-they-will-come. Bootstrapping a community that loves programming in it is the hard part. You'll either need a killer interop story with an already built ecosystem, or you'll need your own HTTP server, JSON parser, etc. etc. etc.
Best of luck! I'll watch this space.
This isn't so much directed at you, as other people that get inspired by this. I have been working on my own Rust like language with claude for a few months and there are a _lot_ of projects like that out there.
Mine has a formally proven borrow checker built on linear types, along with algebraic effects, with an LLVM compiler written in lean -- the type checker uses exactly the proven calculus.
If you are going to build a language with claude, I highly, highly recommend writing it in Lean or Coq and starting by formalizing a pre-existing paper or system that has the properties you want.
Claude gets confused and takes shortcuts constantly, and if you don't have a proven base, you are really going ot struggle. I had to throw away months of work as i got bogged down trying to resolve special cases and bugs that just evaporated when i switched to a proven calculus.
It's so strange how much effort goes into producing a language that people don't even intend to write.
Why optimize for old fashioned manual programming, especially since you are vibe coding the language to begin with? Unless you think Claude and friends will “enjoy” using it more.
