\NB Die senkrechten Striche sind im ersten Beispiel etwas einger"uckt,
da \verb|\mid| als Operator gesetzt wird. Schlie"st man die linke Seite
in \verb|{..}| ein, dann wird |weird| nicht richtig gesetzt. Die rechte
Seite \emph{wird} in \verb|{..}| eingeschlossen, damit |list| und
|main| richtig gesetzt werden (auf diese Weise verliert \verb|\mid|
seinen Status als Operator).
