-Subject: [PATCH 02/13] Add a "fallback" mode for named property interceptors
-
-By default interceptors are called before the normal property
-resolution on objects.  When an interceptor is installed as a
-"fallback" interceptor, it is only called if the object doesn't
-already have the property.
-
-In the case of a global object having an fallback interceptor,
-the interceptor is not invoked at all for var or function
-declarations.
