    Let V8 throw the exception when QML property lookup fails · a27fd584
    Kent Hansen authored
    Only V8 knows whether a failed property lookup should actually cause
    a ReferenceError to be thrown. When evaluating a "typeof" expression,
    for example, a ReferenceError should not be thrown even if the
    expression involves global variables that don't exist, according to
    the ECMA-262 specification.
    
    QML should try to match the standard JavaScript behavior. This is
    achieved by simply returning an empty value handle (to signify the
    absence of the property), and leaving it to V8 to throw an exception
    as appropriate.
