I don't know the answer to you question, but with overloaded functions
or functions that have too many template arguments I sometimes forego
binders and write a small struct to invoke them. It might be something
like this:

template<int Index, class Tuple>
struct  calls_get_t : std::unary_function<..> {
        result_type operator()(argument_type arg) {
                return get<Index>(arg);
        }
};
                
Maybe boost-pros know a better way. Also I am beginning to look at
Fusion which may have some extra functions we can use with tuples.
