 This code doesn't compile.


 {{{
 #include <utility>
 #include <list>
 #include <boost\iterator\transform_iterator.hpp>
 #include <boost\lambda\lambda.hpp>
 #include <boost\lambda\bind.hpp>
 #include <boost\function.hpp>

 int main(int argc, char* argv[])
 {
     using namespace std;
     using namespace boost;
     using namespace boost::lambda;

     typedef list<pair<int, double> > Tlist;

     make_transform_iterator
     (    Tlist().begin(),
          bind(&Tlist::value_type::first, _1)
     );

     return 0;
 }

 But this does:


 {{{
 #include <utility>
 #include <list>
 #include <boost\iterator\transform_iterator.hpp>
 #include <boost\lambda\lambda.hpp>
 #include <boost\lambda\bind.hpp>
 #include <boost\function.hpp>

 int main(int argc, char* argv[])
 {
     using namespace std;
     using namespace boost;
     using namespace boost::lambda;

     typedef list<pair<int, double> > Tlist;

     make_transform_iterator
     (    Tlist().begin(),
          function<int(Tlist::value_type)>
          (  bind(&Tlist::value_type::first, _1)
          )
     );

     return 0;
 }
 }}}
