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