+// std::multiset
+// 
+// const declarations are used to guess the intent of the function being
+// exported; therefore, the following rationale is applied:
+// 
+//   -- f(std::multiset<T>), f(const std::multiset<T>&):
+//      the parameter being read-only, either a sequence or a
+//      previously wrapped std::multiset<T> can be passed.
+//   -- f(std::multiset<T>&), f(std::multiset<T>*):
+//      the parameter may be modified; therefore, only a wrapped std::multiset
+//      can be passed.
+//   -- std::multiset<T> f(), const std::multiset<T>& f():
+//      the set is returned by copy; therefore, a sequence of T:s 
+//      is returned which is most easily used in other functions
+//   -- std::multiset<T>& f(), std::multiset<T>* f():
+//      the set is returned by reference; therefore, a wrapped std::multiset
+//      is returned
+//   -- const std::multiset<T>* f(), f(const std::multiset<T>*):
+//      for consistency, they expect and return a plain set pointer.
