We might need to specify property enumeration order for ECMAScript host objects. https://bugzilla.mozilla.org/show_bug.cgi?id=524423
I added a section on property enumeration: http://dev.w3.org/2006/webapi/WebIDL/#property-enumeration which handles objects with index/name getters. This means that specifications defining interfaces with name getters need to define the order of those names. I'll defer to future ES specifications for property enumeration order of more normal objects.
