Boost :

I see I can get this to work by adding an ugly const_cast. This seems to
confirm my suspicion, that the problem is caused by iterator_facade having
template <class Facade>
      static typename Facade::reference dereference(Facade const& f)
          return f.dereference();

IIUC the problem is the const in the above. To make my adaptor work, I did
    scalar_type & dereference() const {
      return (cnt % 2 == 0) ?
const_cast<complex_type&>(*this->base_reference()).real() :

So, basically, my dereference() has to lie about being const.

Is this really correct? Is there another way to make my dereference without
this ugly cast?
