class hierarchy diagrams are only useful for understanding designs when you 
actually have complex hierarchies. This very conversation is about adding 
features to make it easy for JS programmers to build such hierarchies.  Who 
knows, may e in a few years we will see a resurgence of UML for documenting JS 
designs in which case people may curse us if we choose today to make the 
triangle point the wrong direction ;-)
