I really still feel like I'd rather do this declaratively. I like being able to
see the dom structure in the HTML with the pages. That would also allow you to
tie up the prefs in the html.

+
+    this.pages_.push(new CrSettingsDummyPage());
+
+    for (var i = 0; i < this.pages_.length; i++)
+      this.pages_[i].prefs = this.$.settings;
+  },
+});
