I don't think the rest of those need protecting for Location.  And 
simply making valueOf an own non-configurable property is a lot simpler 
than creating yet another custom [DefineOwnProperty] implementation, at 
least in Gecko, and has the benefit of not being weird magic from the 
point of view of the web page.  I can't speak for other implementations...
