The TR1 Tuple provides the get function to provide access to it's elements by zero based numeric index.
template<int I, T> RJ get(T& t);
Requires: 0 < I <= N. The program is ill formed if I is out of bounds. T is any fusion sequence type, including tuple.
Return type: RJ is equivalent to result_of::at_c<I,T>::type.
Returns: A reference to the Ith element of T.
template<int I, typename T> PJ get(T const& t);
Requires: 0 < I <= N. The program is ill formed if I is out of bounds. T is any fusion sequence type, including tuple.
Return type: PJ is equivalent to result_of::at_c<I,T>::type.
Returns: A const reference to the Ith element of T.
