## What it is
Dyon is a dynamically typed scripting language implemented in Rust, designed for embedding in Rust applications, particularly games in the Piston ecosystem. It ships as a Rust library plus REPL and script runner binaries, with editor plugins for Atom, Vim, and VS Code.

## Use cases
- embed a scripting language in a Rust game
- run dynamically typed scripts from the command line
- try out a scripting language in a REPL
- script game logic without recompiling Rust
- use a scripting language with lifetime checking instead of a garbage collector

## When to choose
- you need an embeddable, dynamically typed scripting layer for a Rust application or game
- you want a small scripting language with Rust-friendly interop via Arc<Mutex<Any>>
- you prefer lifetime/mutability checking over garbage collection in a script language

## When to avoid
- you need a mainstream language with a large ecosystem and community
- you require static typing or compile-time type safety
- you need high-performance compute-heavy scripting comparable to compiled languages

## Facets
- artifact type: library
- maturity: active
- function: interpreter, programming-language
- domain: programming-languages, developer-tools
- platform: rust, cross-platform, cli
