Ember Computed Literal Backwards Compatibility Blocker

[Ember.computed.literal][1] is blocked on a backwards compatibility story. There are basically three options:

1. Breaking change for consistency, deprecating existing behaviour;
2. More complicated temporary solution for backwards compatibility (ember only); and
3. More complicated temporary solution for backwards compatibility (ember and ember-cpm).

TL;DR

1. user.get('posts') should resolve as soon as the ids are known, possibly before the records are loaded;
2. user.get('posts').objectAt(0) should return a PromiseObject and also fetch that object;
3. The fetches from #2 should be coalesced and;
4. user.get('posts').load() should fetch the records and return a promise that resolves when they are all loaded.

Consider the example:

var MyObject = Ember.Object.extend({
  selectedContent: Ember.computed.filterBy('content', 'isSelected')
});

var obj = MyObject.create({
  content: [
    Em.Object.create({name: "one", isSelected: false}),
 Em.Object.create({name: "two", isSelected: false})
