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