     var w = new Widget()
       .setVolume(...)
-      .setDensity)(...)
+      .setDensity(...)

 If you later call `w.initialize()`, it won't be initialized again. You need a named `once`, because an ordinary `once` would be called once for every instance sharing the same prototype, whereas the named once will keep track of whether it has been run separately for each instance.
 
-Caveat: Every instance will have a `__once__` property. If you later write code that iterates over every property, you'll have to take care not to interact with it.
