// defined on that interface, as described in sections 3.6.6 Constants and
// 3.6.8 Operations.

// If the interface is declared with a [Constructor] extended attribute,
// then the interface object can be called as a constructor to create an
// 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.
//
// An interface object for a non-callback interface has an associated object
// called the interface prototype object. This object has properties that
// correspond to the regular attributes and regular operations defined on
// the interface, and is described in more detail in 3.6.3 Interface
// prototype object.
