Suppose I have the following structure:

struct xy { int x, y; };

and the following vector:

vector<xy> v(10);

I want to use lambda library for find an item in the table. Let's say, with x member value equal to 10. Something like this doesn't work:

pos = find_if(v.begin(), v.end(), _1.x == 10);

How the above line should be written ?

Operator . is not overloadable, so the above cannot work. The lambda expression should be: bind(&xy::x, _1) == 10 Jaakko
