What is the idiomatic way to write

```nohighlight
myObserver: function() {
// Some stuff here
}.observes('x').on('init')

```

without function prototypes?

Hello, try this one:

```
myObserver: Ember.on('init', Ember.observer('x', function () {
    // Some stuff here
}))

```

Thank you, @od1n, I have similar code but I thought there might be some nicer way. Guess we’ll need to wait for the decorator implementation 😄

Thank you!
