// object that implements that interface. Calling that interface as a
// function will throw an exception.
// Interface objects whose interfaces are not declared with a [Constructor]
// extended attribute will throw when called, both as a function and as a
// constructor.

// called the interface prototype object. This object has properties that

// the interface, and is described in more detail in 3.6.3 Interface
// prototype object.
