..as for the iterators - just typedef them:
template <typename T> myList {
public:
typedef std::list<T> MyListType;
MyListType::const_iterator const_iterator;
const_iterator begin() const { return theList.begin(); }
const_iterator end() const { return theList.end(); }
private:
MyListType theList;
MyListType::iterator iterator;
iterator begin(){ return theList.begin(); }
iterator end() { return theList.end(); }
};
