The Lambda version would be similar, just replacing the outer bind with infix notation

#include "boost/lambda/lambda.hpp" #include "boost/lambda/bind.hpp"

using namespace boost::lambda;

std::accumulate( begin, end, _1 + bind(&A::a, _2 ));

Again untested.

this std::accumulate return complicated lambda function, but not int value :-)

Yeah, sorry, missed the initial value! std::accumulate( begin, end, 0, _1 + bind(&A::a, _2 ));
