-\subsection{Example sequence}
-
-This section lists an example expression, with a sequence of transforms
-applied to it. The exact transforms given here probably don't exactly
-match the transforms given above anymore, but perhaps this can clarify
-the big picture a bit.
-
-TODO: Update or remove this section.
