Rob -

I highly recommend moving to phoenix (despite comments made later in 
this thread). The library is extremely powerful and stable and has been 
conditionally accepted ( 
<http://lists.boost.org/boost-announce/2008/10/0205.php> ). The 
documentation is excellent and the support is speedy. I find phoenix 
constructs to be far more readable than boost.lambda resulting in 
overall improved understanding of the code's intent.

Documentation can be found here: 
<http://www.boost.org/doc/libs/1_42_0/libs/spirit/phoenix/doc/html/index.html>

Here is your example using phoenix -------------------

#include <iostream>
#include <vector>
#include <boost/spirit/include/phoenix.hpp>

int main()
{
   using namespace boost::phoenix::arg_names;
   std::vector< int > vec;

   // fill the vector with something
   for( int i=0; i < 10; ++i )
   {
      vec.push_back( i );
   }

   // double them all
   std::for_each( vec.begin(), vec.end(),
          ( arg1 *= 2 )     );

   // print them all out
   std::for_each( vec.begin(), vec.end(),
          ( std::cout << arg1 << " " )      );

   std::cout << std::endl;
  
   return 0;
}

Hope this helps some -
