 \returns
-Let \tcode{o1} be the iterator past the last copied element
-in the output range \range{out_true}{last_true},
-and \tcode{o2} be the iterator past the last copied element
-in the output range \range{out_false}{last_false}.
+Let \tcode{$Q$} be the number of elements copied
+into the output range \range{out_true}{last_true},
+and \tcode{$V$} be the number of elements copied
+into the output range \range{out_false}{last_false}.
 Returns:
 \begin{itemize}
-\item \tcode{\{o1, o2\}} for the overloads in namespace \tcode{std}.
-\item \tcode{\{first + $N$, o1, o2\}} for the overloads in namespace \tcode{ranges}.
