Oh ok. Yeah I saw that change in 0.2.3 release notes but somehow didn't realize that it will impact callback methods too.
I somehow feel though that the reflection of values should be default on, while opt out should be an option too. I understand there's probably some performance impact, not sure how big, but having default off is slightly un-intuitive and inspecting DOM during debug process gets harder too. May be other option is to just have a global reflect property that could be set/unset for debugging purposes. One of the cases where I ran into this was in a child element that wants to watch changes to all attributes of a parent element. What's the best way to achieve this in a way such that the child callback always happens no matter how the change watcher is defined on parent for the attributes? i was using attributeChanged callback method on the child, but I think that's not the best way because attributeChanged won't be called if a more specific observer is defined for an attribute by the parent. May be, in the child element, I should attach another Object observer to the instance to watch for specific changes.
