OvermindDL1, you are right,
while lambda with units needs to explicitly  to #include<boost/units/
lambda.hpp>
boost phoenix works out of the box

        cout<< (boost::lambda::_1+boost::lambda::_1)(energy) <<endl;  //
needs #include "boost/units/lambda.hpp"
        cout<< (boost::phoenix::arg_names::arg1 +
boost::phoenix::arg_names::arg1)(energy) <<endl;
