## Implementation

    void forEach(void action(E entry)) {
      int modificationCount = _modificationCount;
      if (isEmpty) return;

      E current = _first;
      do {
        action(current);
        if (modificationCount != _modificationCount) {
          throw ConcurrentModificationError(this);
        }
        current = current._next;
      } while (!identical(current, _first));
    }
