* Freely pass Rust variables/constants into a script via an external [`Scope`](https://rhaiscript.github.io/book/rust/scope.html) - all clonable Rust types are supported; no need to implement any special trait.
* Easily [call a script-defined function](https://rhaiscript.github.io/book/engine/call-fn.html) from Rust.
* Relatively little `unsafe` code (yes there are some for performance reasons).
* Few dependencies (currently only [`smallvec`](https://crates.io/crates/smallvec)).
* Few dependencies (currently only [`smallvec`](https://crates.io/crates/smallvec) and [`fxhash`](https://crates.io/crates/fxhash)).
* Re-entrant scripting engine can be made `Send + Sync` (via the `sync` feature).
* Scripts are [optimized](https://rhaiscript.github.io/book/engine/optimize.html) (useful for template-based machine-generated scripts) for repeated evaluations.
* Easy custom API development via [plugins](https://rhaiscript.github.io/book/plugins/index.html) system powered by procedural macros.
