+		  (variable size, less storage for large sparse sets).
+                  Faster than BITSET_LIST for random access.
+   BITSET_VARRAY: Variable array of bits (variable size, fast for
+                  dense bitsets).
+   BITSET_STATS:  Wrapper bitset for internal use only.  Used for gathering
+                  statistics and/or better run-time checking.
