The `@Override` annotation has been inconsistently applied in the collections implementations. In practice since so many methods are overridden, and some test would likely fail if a method weren't overridden properly, the annotation would mostly add clutter. Indeed I'm considering pulling out all uses of `@Override` in certain areas because they're just clutter.
