\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(); }
