I wish this is landing in Canary ASAP, I understand everything is doable
through Proxy but:
1. Proxy is nowhere, Proxy is more complicated
2. Proxy means dealing with objects wrappers and wrappers owners,
Object.observe deals with the object everyone is using, not its own wrap
3. using some sort of "ticks based events queue", combined with DOM
mutation events, Object.observe is way easier to shim while Proxy are
impossible to shim
This Object.observe "unaccepted" strawman thing, is the best proposal I
have seen in a while ... I am all in for := , class, super and stuff, but
that's not really what nowadays web applications need, Object.observe is,
and this is, of course, just my opinion.
