+\Large\sloppy
+The first macro applies a transformation to a
+\flip{text} object, the second applies a
+color (\red{red online}, \red{gray in print}).
+If used separately, they work just fine.
+If used as \verb|\flip{\red{text}}|, it's
+still ok: \flip{\red{text}}. Now try to say
+\verb|\red{\flip{text}}|: \red{\flip{text}}.
+The text is transformed and colored as
+expected. But all the rest of the page is
+broken, as its content is completely
+displaced!
