 The `@unboxed` decorator provides a way to unwrap **variant** constructors
-that have a *single* argument, or **record** objects that have a *single* field.
+that have no overlap in their runtime representation, or **record** objects that have a *single* field.
 
 ### Example
 
 <CodeTab labels={["ReScript", "JS Output"]}>
 
 ```res
 @unboxed
-type name = Name(string)
+type listItemValue = String(string) | Boolean(bool) | Number(float)
+let myArray = [String("Hello"), Boolean(true), Boolean(false), Number(13.37)]
 let studentName = Name("Joe")

 </CodeTab>
 
+_`@unboxed` for variants with multiple constructors is available since ReScript `11.0.0`._
