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