+  24.1.2 The ArrayBuffer Constructor
+
+  ...
+
+  The ArrayBuffer constructor is designed to be subclassable. It may be used as
+  the value of an extends clause of a class definition. Subclass constructors
+  that intend to inherit the specified ArrayBuffer behaviour must include a
+  super call to the ArrayBuffer constructor to create and initialize subclass
+  instances with the internal state necessary to support the
+  ArrayBuffer.prototype built-in methods.
