FTR, I haven't proposed anything just yet :)
Although if I did, I think I would be more fond of something like:
```js
Object.mixin({ foo: 'bar' }, EventEmitter);
```
... that is, I can see the value of events as an object-level API that
doesn't imply actual inheritance from something else. The use of `mixin`
is probably a distraction here, but the main point is that it's opt-in.
Events inherently have semantics around them, and they're certainly not
universal semantics for objects. In fact, event semantics aren't even
universal for events (e.g., bubbling). It seems better to me to have some
sort of explicit contract before those semantics kick in.
