// std::array
// 
// The aim of all that follows would be to integrate std::array with 
// as much as possible, namely, to allow the user to pass and 
// be returned tuples or lists.
// const declarations are used to guess the intent of the function being
// exported; therefore, the following rationale is applied:
// 
//   -- f(std::array<T, N>), f(const std::array<T, N>&):
//      the parameter being read-only, either a sequence or a
//      previously wrapped std::array<T, N> can be passed.
//   -- f(std::array<T, N>&), f(std::array<T, N>*):
//      the parameter may be modified; therefore, only a wrapped std::array
//      can be passed.
//   -- std::array<T, N> f(), const std::array<T, N>& f():
//      the array is returned by copy; therefore, a sequence of T:s 
//      is returned which is most easily used in other functions
//   -- std::array<T, N>& f(), std::array<T, N>* f():
//      the array is returned by reference; therefore, a wrapped std::array
//      is returned
//   -- const std::array<T, N>* f(), f(const std::array<T, N>*):
//      for consistency, they expect and return a plain array pointer.
