Fuse 是一门静态类型纯函数式语言,支持高阶类型和特设多态,通过 GRIN 全程序优化器生成 LLVM 原生代码。对受够了 Haskell/GHC 编译速度或想探索函数式语言后端优化的工程师,这是一个值得关注的实验性实现。

GRIN 作为后端比 GHC 的 STG 机器更激进地做全程序 deforestation 和堆分配消除,但之前只有科研原型(如 Boquist 的论文实现)。Fuse 把它产品化的同时保留了 Haskell 风格的类型系统,这填补了轻量函数式语言 + 激进优化后端之间的空白。

跟 Haskell 比,Fuse 语法更简洁(无显式 module 声明、更轻量的 trait 系统),但生态成熟度是零;跟 Rust 比,它有真正的高阶类型但放弃了所有权模型。最该关注的是做语言设计或编译器后端的人——GRIN 的优化管线可以直接拿来对比测试自己的 IR 设计。

核心争论:语法设计取舍:借鉴 Rust 风格还是遵循 Haskell 传统,类型参数用 [] 还是 <>

It's nice to see a GRIN backend in the wild! It looks like a tidy little functional language - a small, easily grasped syntax surface and generally clear semantics. That you've got it to the point that it can compile and run proper programs is a great achievement for a solo dev project! The string t

First of all thanks for all the feedback and looking into it, appreciate it! Yeah GRIN is a great project, it took a lot of debugging and analysis to make it compile 100% especially with monomorphization involved. I'll look into Unicode support, makes total sense. Didn't scope it in initially. I can

I’d really encourage you with Unicode support, as frustrating as of a side track it may be - I’ve had fun dogfooding my hobby languages by writing small web servers and CLI utilities. Even if it just generates part of your shell prompt!
