`observesImmediately` will maintain the synchronous behavior.

/**
The `on` extension of Javascript's Function prototype is available
when `EmberENV.EXTEND_PROTOTYPES` or `EmberENV.EXTEND_PROTOTYPES.Function` is
true, which is the default.
You can listen for events simply by adding the `on` call to the end of
your method declarations in classes or mixins that you write. For example:
```javascript
Ember.Mixin.create({
doSomethingWithElement: function() {
// Executes whenever the "didInsertElement" event fires
```
Internally, `Ember.onerror` is used as Backburner's error handler.
@event onerror

@param {Exception} error the error object
