Re: NULL pointers and None type

You need to change your declaration to

class Iterator
{
  public:
      Iterator(CObject *O);
            void Next(void);

      CObject * Obj;
     };

ie, you need to use pointer instead of references.

This is not a swig constrain, it is a C++ one: when
you use reference, you can't pass a null value, or
you will get a seg. fault.
