+//! Render Macros Module
+//!
+//! This module provides procedural macros for rendering operations.
+//! These macros expect a mutable reference to a `RenderResult` named `r` to be in scope.

+/// Implementation of the `r_print!` procedural macro
+///
+/// This macro expands to a call to `RenderResult::print` with formatted arguments.
+/// It expects a mutable reference to a `RenderResult` named `r` to be in scope.
+///
+/// # Examples
+///
+/// ```ignore
+/// use mingling_macros::r_print;
+///
+/// let mut r = RenderResult::default();
+/// r_print!("Hello, {}!", "world");
+/// ```

+        Ok(args) => args,
+        Err(e) => return e.to_compile_error().into(),
