He had led in to a section on "Other MVC Frameworks". Then a single slide with some code along these lines:

  Todo = OtherMVC.Model.extend({
    clear: function() { this.view.remove(); }
  });

  TodoView = OtherMVC.View.extend({
    initialize: function() { this.model.view = this; }
  });

Basically he ragged on that for breaking MVC, and never mentioned Backbone by name. I spoke to him afterwards, and he seemed pretty set against Backbone. He considers manually bubbling events to be tedious: "not the happy path".

I've been inspired by Morphic recently, where models having knowledge of their views makes sense. When I was a beginner though, I was briefly puzzled by how to connect multiple views to a model and vice versa: I first tried to extend the pattern above before binding to model events.
