Show HN: Fuse – statically typed functional programming language

Hacker News - Sun, 08/02/2026 - 7:23am

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 extending with concepts such as Bidirectional Type Checking with Higher-Rank Polymorphism.

I’ve mainly drawn inspiration from Rust, Haskell, Scala and Python (in terms of syntax). It all started because I wanted a language that has Rust-like concepts such as: ADT, Traits, Impl block syntax, etc. but have the pure functional semantics.

I'd would love feedback on the language design and its general usage.

Show HN: Vein, a minimalist open-source resource management game

Hacker News - Sun, 08/02/2026 - 5:44am

Recently I've been working on Vein, a small open-source resource management game built with Godot.

I've always loved resource management board games, and I wanted to see how minimal I could make one. The core idea is simple: keep the heart beating by supplying it with the resources it demands. I tried to strip the mechanics down as much as possible while still leaving room for interesting decisions, and I added a short tutorial to help players get started.

The problem is that I still don't feel like I've found the right gameplay loop. It works, but it isn't yet the game I imagined. I'd really appreciate any feedback—whether it's about the mechanics, pacing, tutorial, UI, or anything else that stands out. I'm especially interested in ideas for making the core loop deeper without making the game more complicated.

Most of the development was done with Claude Sonnet as a coding partner, while I focused on the design, gameplay, and iteration. The game engine is Godot.

I'd love to hear what you think.
