+  25.4.3 The Promise Constructor
+
+  ...
+
+  The Promise constructor is designed to be subclassable. It may be used as the
+  value in an extends clause of a class definition. Subclass constructors that
+  intend to inherit the specified Promise behaviour must include a super call
+  to the Promise constructor to create and initialize the subclass instance with
+  the internal state necessary to support the Promise and Promise.prototype
+  built-in methods.
