## What it is
Gluon is a small, statically-typed functional programming language with type inference, implemented in Rust and designed for embedding in applications as a scripting layer. It provides a Rust library with a simple embedding API, a REPL, and thread-safe parallel execution of scripts.

## Use cases
- embed a scripting language in a Rust application
- add user-configurable scripts to my program
- run sandboxed functional scripts with static types
- evaluate expressions at runtime from Rust
- try a small ML-like language in the browser
- script game or app logic without recompiling

## When to choose
- you need an embeddable scripting language in a Rust codebase with minimal marshalling boilerplate
- you want static typing and type inference for embedded scripts
- you need thread-safe parallel execution of scripts with separate heaps

## When to avoid
- you need a mature general-purpose scripting language with a large ecosystem like Lua or Python
- your project is not written in Rust
- you need extensive third-party libraries or tooling for the scripting layer

## Facets
- artifact type: library
- maturity: active
- function: programming-language, interpreter, compiler, type-system
- domain: programming-languages, developer-tools, parsers
- platform: rust, cross-platform, cli
- tags: scripting-language, embeddable, functional-programming, type-inference, repl, garbage-collected
