+/**
+ * This selector is here just to shake up your thinking a bit. Don't get
+ * too caught up in boolean, there are other ways you can evaluate a
+ * collection of selectors. This one takes a vote of the selectors it
+ * contains, and majority wins. You could also have an "all-but-one"
+ * selector, a "weighted-average" selector, and so on. These are left
+ * as exercises for the reader (as are the usecases where this would
+ * be necessary).
