 ### Subclassable Built-ins
 In ES6, built-ins like `Array`, `Date` and DOM `Element`s can be subclassed.
 
-Object construction for a function named `Ctor` now uses two-phases (both virtually dispatched):
-- Call `Ctor[@@create]` to allocate the object, installing any special behavior
-- Invoke constructor on new instance to initialize
-
-The known `@@create` symbol is available via `Symbol.create`.  Built-ins now expose their `@@create` explicitly.
-
 ```JavaScript
-// Pseudo-code of Array
-class Array {
-    constructor(...args) { /* ... */ }
-    static [Symbol.create]() {
-        // Install special [[DefineOwnProperty]]
-        // to magically update 'length'
-    }
-}
-
-// User code of Array subclass
+// Array subclass
 class MyArray extends Array {
     constructor(...args) { super(...args); }
 }
 
-// Two-phase 'new':
-// 1) Call @@create to allocate object
-// 2) Invoke constructor on new instance
 var arr = new MyArray();
 arr[1] = 12;
-arr.length == 2
+arr.length == 2;
+
+Array.isArray(arr); // true
 ```
