They are already in, according to the html-september draft
found at cygnus. Except erase() is called clear(). One example:

  23.2.3  Template class list                       [lib.list]
  ...
  namespace std {
    template <class T, class Allocator = allocator>
    class list {
      ...
    // _lib.list.cons_ construct/copy/destroy:
      ...
      template <class InputIterator>
        void assign(InputIterator first, InputIterator last);
      template <class Size, class T>
        void assign(Size n, const T& t = T());
      ...
    // _lib.list.modifiers_ modifiers:
      ...
      void clear();
