Fuse - Statically typed functional programming language

Show HN: Fuse – statically typed functional programming language

Fuse is a statically typed, purely functional language that combines modern type system features with clean syntax inspired by Rust, Python, Scala, and Haskell. It offers higher-kinded types, ad-hoc polymorphism, and type inference, allowing developers to write expressive and composable code. Fuse compiles through the GRIN whole-program optimizer and LLVM to produce fast, small native binaries with zero-cost abstractions. Ideal for developers seeking a functional language with strong type safety and high performance, Fuse is available for Linux and macOS with a simple one-line installer.

Fuse brings the power of higher-kinded types and ad-hoc polymorphism to a purely functional language, compiling to fast native code via GRIN and LLVM.
