std::bind2nd problem

   Lets look at code:

#include <algorithm>
#include <functional>
#include <vector>

class example {
public:
    bool predicate(const int&) {
        return true;
    }
};

void fun() {
    std::vector<example> coll;
    std::find_if(coll.begin(), coll.end(),
std::bind2nd(std::mem_fun_ref(&example::predicate), 10));
}

   Compilation of this code failes (GCC, MSVS) because "predicate"
gets "const int&" and "bind2nd" adds to this type another "const _ &"
which gives reference to a reference. Obviously changing type to "int"
instead of "const int&" does the trick, but in my code I have to deal
with a type with copy operator which I would like to avoid calling.
What can be done? Anything? I tried specifieng appropriate types "by
hand" when sepcializing templates but I always ended with a different
compilation error (no conversions...).
