\me ponders running out to buy MW 8.2 just to get this working...

Yet one more idea (arghhhhh):

template<typename T>
struct dummy {
  void nonnull();
};

typedef void (dummy<int>::*safe_bool)();

operator safe_bool() const
  { return this->empty? 0 : &dummy<int>::nonnull; }

bool operator!() const
  { return this->empty(); }
