Mainly to use a more normal constructor declaration and to enable classes with more than one template parameter to be used as container types.

// -- 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.
