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)); } };

Yep. Boost.Fusion has several such utilities ...

Thanks Eric, I'll take a look. Jeff
