composite keys

[stefanpenner]

something like:

stateFor(['some-string', obj1, obj2, obj3])

and the key derived is basically array.map(Ember.guid).join(0x00)
and the auto-eviction is complicated, but likely possible to derive or some delegation back to the user can be provided.

after discussion with @stefanpenner today:

Ember.Component.extend({
  firstName: 'bob',

  data: stateFor('state-name', 'primary-key', {
    secondaryKeys: ['foo', 'bar', 1, true],
    scoped: ['firstName']
  })
});

mapKey = GUID('foo') + GUID('bar') + GUID(1) + GUID(true);
