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