Hi!

This one works...

#include <boost/lambda/lambda.hpp>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/construct.hpp>
#include <algorithm>
#include <vector>

struct A
{
      A(int)   {}
      void f()const {}
};

int main( )
{
      using namespace boost::lambda;

      std::vector< int > v;
      std::for_each( v.begin( ), v.end(), bind(&A::f,
bind<A>(constructor<A>(), _1)));
}

Regards,
Ovanes
