lambda library bug --- endl?

Hi there.

I have a recent CVS version of Boost installed, and am using g++ v3.2.  I
tried to compile the following program:

-----------lambda_test.cpp------------
#include <iostream>
#include <string>
#include <list>
#include <algorithm>
#include <boost/lambda/lambda.hpp>

using namespace std;
using namespace boost::lambda;

int main() 
{
    list<int> ell;
    
    for (int i=0; i<100; ++i)
        ell.push_back(4*i-1);

    for_each(ell.begin(), ell.end(), cout << _1 << endl);
}
--------------------------------------

I am met by:

% g++ -I/usr/local/boost -c lambda_test.cpp
lambda_test.cpp: In function `int main()':
lambda_test.cpp:17: no match for `const
boost::lambda::lambda_functor<boost::lambda::lambda_functor_base<boost::lambda::
bitwise_action<boost::lambda::leftshift_action>,
   boost::tuples::tuple<std::ostream&, 
   boost::lambda::lambda_functor<boost::lambda::placeholder<1> >, 
   boost::tuples::null_type, boost::tuples::null_type, 
   boost::tuples::null_type, boost::tuples::null_type, 
   boost::tuples::null_type, boost::tuples::null_type, 
   boost::tuples::null_type, boost::tuples::null_type> > > << <unknown type>' 
   operator

Any suggestions?  I am aware that I can replace endl by '\n' and get a
compilable program.  I worry that this problem extends to other
manipulators...

Thanks,
Ken
