Oh, of course!  Now that I see it, it makes perfect sense.  For some reason, 
I was thinking that I needed placeholders for all values being passed to the 
functor, when all I really needed was the placeholder for the element in the 
vector because I have the actual values for the 2nd and 3 parameters.

I just have to add:

    typedef bool result_type;

to my functor, or call boost::bind<bool>.

Thanks!
