Try using boost::function<bool(int)> for the predicate type.

Thank you Steven. Using boost::function as the predicate type does the trick. For the sake of completeness, I post some code at the bottom. I think this is a very useful method to provide filtered values to a user, without copying any elements.

Copying is of course only avoided if the Predicate function is defined as boost::function<bool(const T&)> PredFunction. James
