Cannot access dataset deferred unless it's passed in.

[alexgraul]

So to be able to access to the deferred before fetch you need to manually pass it in

new Miso.Dataset({
  data : ...,
  deferred : new _.Deferred()
});

This works but is unnecessary. Deferred should be created on instantiation if not passed in and be accessible. This is needed as promise returned from fetch might be resolved before all its done handlers can be bound.

Will move deferred to instantiation from fetch
