Struct NativeFn 

pub struct NativeFn {
    pub name: Arc<str>,
    pub arity: Arity,
}

A host-registered Rust function exposed to Lisp code. The actual callable lives in the Interpreter<H>’s FnRegistry, keyed by name — this struct carries just the lookup key and arity so Value remains non-generic over H.

Fields
