Which of the following to you find more readable? The hand-written loop:

for (std::vector<Foo>::const_iterator it = vec.begin(); it != vec.end(); ++it)
{
    bar.process(*it);
}

Or the algorithm invocation:

#include <algorithm>
#include <functional>

std::for_each(vec.begin(), vec.end(),
              std::bind1st(std::mem_fun_ref(&Bar::process), bar));

I wonder if std::for_each is really worth it, given such a simple example already requires so much code.

What are your thoughts on this matter?
