-\dfn{nth}{list i}{object}{procedure \textbf{(obsolete)}}
-\begin{desc}
-Returns the $i^{\mathrm th}$ element of \var{list}.
-The first element (the car) is \ex{(nth \var{list} 0)},
-the second element is \ex{(nth \var{list} 1)}, and so on.
-
-This procedure is provided as it is useful for accessing elements
-from the lists returned by the field-readers (chapter~\ref{chapt:fr-awk}).
-
-The functionality of \ex{nth} is equivalent to that of \RnRS{}'s
-\ex{list-ref}.  Therefore, \ex{nth} will go away in a future release.
