I suggested this to TC39 a while back and I still think it's a good idea even though reception was lukewarm at best (the people replying didn't like to acknowledge the existence of this seemed like). They should define this as a primitive of the Object type and define which objects support it and how. The monkey patching we do now is not great. -- http://annevankesteren.nl/
