[boost] Recovering a function object after bind

I'm trying to use bind with for_each but I need a copy of the bound function
object back after for_each. I've tried using boost::ref(f) but that just
gives me a compiler error (CW 7.2) that the result type isn't defined
(apparently on the wrapped reference.

...
    Function f;
    // How do I get a copy of f back?
    ??? = std::for_each(first, last, boost::bind(f, _1));
...

...
    // This won't compile
    Function f;
    std::for_each(first, last, boost::bind(boost::ref(f), _1));
    return f;
...

Any ideas?
Thanks,
Sean
