 example, following
 \begin{verbatim}
 \NewDocumentCommand\foo{om}{I grabbed `#1' and `#2'}
+\NewDocumentCommand\baz{o}{#1-#1}
 \end{verbatim}
 using the command as
 \begin{verbatim}
-\foo[[some stuff]]{more stuff}
+\foo[\baz[stuff]]{more stuff}
 \end{verbatim}
 will print
 \begin{quote}
-I grabbed `[some stuff]' and `more stuff'
+I grabbed `stuff-stuff' and `more stuff'
 \end{quote}
 This is particularly useful when placing a command with an optional argument
 \emph{inside} the optional argument of a second command.
