#include <boost/lambda/lambda.hpp>
#include <boost/bind.hpp>
#include <boost/mem_fn.hpp>

int main()
{
        using boost::bind;
        using boost::mem_fn;

        A a1("str1", "str2", "str3");
        A a2("str2", "str1", "str3");

        eval(((bind(&A::s1, _1) < bind(&A::s1, _2)) && (bind(&A::s2, _1)
< 
bind(&A::s2, _2)))(a1, a2));
}

This errors compiling about operator&& no match found. 

[Nat] I think the problem may be that you're mixing boost::bind with
plain operators. Try using boost::lambda::bind instead and see if you
get farther.
