In plain words
This is a dependently typed programming language designed to teach proof writing through implementation. It allows developers to write formal proofs by leveraging dependent types, where types can depend on values. The language is intentionally minimal, enabling someone to build a working implementation in a single day. It targets programmers and computer science students interested in learning type theory and formal verification without the complexity of established proof assistants.

ScrapScript – A tiny functional language for sharable software2023 · scrapscript.org · ▲503Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at [email protected] if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :)

Hi HN! I've been working on the fuse programming language, it's a statically typed purely functional language with higher-kinder types and ad-hoc polymorphism. It compiles to the GRIN whole-program optimizer, producing LLVM-generated native code. Fuse supports ADTs, Generics, Type Methods, Traits, Pattern matching etc. all in a functional style with no mutations. I’ve been developing the language for 5 years, with code written in Scala. I’ve started coding the language from the base of System F that was implemented as part of the book: Types and Programming Languages (tapl). And then…
