+                This object is basically a type-safe version of a void*.  In particular,
+                it is a container which can contain only one object but the object may
+                be of any type.  
+
+               <p>
+                It is somewhat like the <a href="#type_safe_union">type_safe_union</a> except you don't have to declare 
+                the set of possible content types beforehand.  So in some sense this is 
+                like a less type-strict version of the type_safe_union.
