+values.  Within an enumeration, the members can be compared by identity, and
+the enumeration itself can be iterated over.  There is built-in support for
+unique values, multiple values, auto-numbering, and suspension of aliasing
+(members with the same value are not identical), plus the ability to have
+values automatically bound to attributes.")
