Hi all.

Is it a correct usage of default constructor of iterators? Are any
gurantees that it will always equals to the iterator returned by
end()? :

       typedef boost::unordered_map<std::string, int> map;
       map x;
       x["one"] = 1;

       assert(x.find("missing") == x.end());
       assert(x.find("missing") == map::iterator());
       assert(map::iterator() == x.end());
