What would be useful is a generic function object whose argument is the 
tuple from above and can forward to a supplied function whose arguments 
are the individual values from the tuple.

Something that keeps me from littering my code with custom functions ala:

void existing_function(const T1&, const T2&, const T3&);

struct tuple_adaptation_of_existing_function
{
    void operator()(const tuple<T1, T2, T3>& t) const
    {
       existing_function(get<0>(t), get<1>(t), get<2>(t));
    }
};
