[Boost-users] Boost lambda: iter_swap and treating lambda as iterator.

K the question is simple. How do i do iterator swap with lambda. lets say i have vector of U. vector<U> vecU; typedef vector<U>::iterator iter; iter beg(vecU.begin()); for_each(vec.begin(), vec.end(), ( if_(_1 == *beg) [ // swap the iterator between the current one and begin. ] ) );
