+    /// ```rust

+    ///
+    /// It does NOT include any other logic such as preserving other colors, or handling newlines.
+    /// If you need newlines in your constant you should use the concat! macro:
+    ///
+    /// ```rust
+    /// use bullet_stream::important_lit;
+    ///
+    /// const DEBUG_INFO: &str = concat!(
+    ///     important_lit!("Debug info:"), "\n",

+    /// ```
+    ///
+    /// Note, if you try to use it like `format!` by accident, it will return the wrapped literal
+    /// and not embed the replaced values:
+    ///
+    /// ```rust
+    /// use bullet_stream::important_lit;
