Fo (Functional Go) is an experimental programming language that extends Go with generics, including generic named types, functions, and methods, while remaining a superset of Go syntax. It ships as a simple compiler CLI that runs single .fo files and an online playground.

Use cases

• add generics to Go programs
• write functional programming style code in Go
• try generic types and methods not possible in standard Go
• experiment with a Go-like language without installing anything via the playground
• study or hack on the Go compiler and ASTs
• run a single-file Go program with type parameters

When to choose

• You want to explore generics syntax in Go on a small, single-file program
• You are interested in modifying the Go compiler or working with Go ASTs
• You need generic methods or omitted receiver type parameters, which standard Go does not support

When to avoid

• You need generics in production Go — use the built-in generics in Go 1.18+
• You are building any real-world application — Fo only compiles one file at a time and is unstable
• You need an actively maintained language or toolchain — the project is explicitly no longer maintained
