Hello Eric, can you provide some hints why this is not possible? For example, can't we use some (boost::?)typeof logic to fetch the iterators type? ;-)
Even if you were willing to accept that, in order to use this macro, you may have to register types with BOOST_TYPEOF (an interface I'm not overly fond of), there are still problems. Registering types for iterators is notoriously difficult. How would you write the BOOST_TYPEOF registrations for the std::vector iterators, for instance, considering that they could very well be defined as: namespace std { template<class T, class Al> struct vector { struct iterator { //... }; }; } // register std::vector<T,Al>::iterator BOOST_TYPEOF_REGISTER_TYPE(?????)
