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!
