+/// list.
+///
+/// Each rule entry is an expression evaluated as
+/// `Box::new(super::rules::<expr>)`, supporting both bare unit struct names and
+/// constructor calls with arguments.
+///
+/// # Example
+///
+/// ```ignore
+/// export_profile! {
+///     MyProfile => "my-profile" {
+///         SomeRule,
+///         AnotherRule::new("arg"),
+///     }
