I don't know why it hasn't gotten into Harmony yet. Sorry I the property descriptors thing is just for library writers I guess, it's too complicated for app devs. I think what's missing is Object.extend: http://www.prototypejs.org/api/object/extend http://api.jquery.com/jQuery.extend/ http://dojotoolkit.org/reference-guide/dojo/extend.html http://docs.sencha.com/ext-js/4-0/source/Object2.html#Ext-Object-method-merge http://code.google.com/p/fbug/source/browse/branches/firebug1.9/content/firebug/lib/object.js just some examples in a few minutes. With extend, then we can write var bar = Object.extend(Object.create(aMethodList), aPropList); jjb
