what does g++ want from my code

[Elazar Leibovich]

template <class a, class b>

class c

{

      private:

              b defaultVal;

      public:

              std::map<a,b> mymap;

             const b &func(a idx)

             {

                 typename std::map<a,b>::iterator it(mymap.find(idx));

                     if (it!=mymap.end())

                             return it->second;

                     else

                             return defaultVal;

             }

};


The compiler is not sure std::map<a,b>::iterator is a typename or a value.
