I have Boost 1.33.1 installed. I'm trying to use Boost.Lamda.

I included all the headers mentioned in the documentation as an
attempt to fix the compile error.

#include <boost/lambda/lambda.hpp>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/loops.hpp>
#include <boost/lambda/algorithm.hpp>
#include <boost/lambda/if.hpp>
#include <boost/lambda/switch.hpp>
#include <boost/lambda/construct.hpp>
#include <boost/lambda/casts.hpp>
#include <boost/lambda/exceptions.hpp>
#include <iostream>
#include <list>

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

   list<int> v(10);
   for_each(v.begin(), v.end(), _1 = 1);

% g++ lambda.cpp
lambda.cpp: In function `int main()':
lambda.cpp:20: error: `_1' undeclared (first use this function)
lambda.cpp:20: error: (Each undeclared identifier is reported only once for
   each function it appears in.)

Using gcc 3.3.1.

Any ideas?
