+/// A procedural macro to reduce boilerplate when defining an Intermediate Representation (IR).
+///
+/// It generates an enum for the IR, along with `Ref` and `Mut` variants,
+/// `From` implementations, and a `ToIr` trait.
+#[proc_macro]
+pub fn ir(input: TokenStream) -> TokenStream {

+
+/// A procedural macro attribute to simplify the definition of built-in functions.
+///
+/// It generates the necessary boilerplate to wrap functions and expose them
+/// to the evaluation engine, handling argument type conversions and arity checking.
