+#  The <code>Enumerable</code> mixin provides collection classes with
+#  several traversal and searching methods, and with the ability to
+#  sort. The class must provide a method <code>each</code>, which
+#  yields successive members of the collection. If
+#  <code>Enumerable#max</code>, <code>#min</code>, or
+#  <code>#sort</code> is used, the objects in the collection must also
+#  implement a meaningful <code><=></code> operator, as these methods
+#  rely on an ordering between members of the collection.
