Issue 129: ClassLayout.description type signature is wrong http://code.google.com/p/xmonad/issues/detail?id=129 New issue report by andrea.rossato: The type signature of ClassLayout.description, presently layout a -> String, makes layout composition at the class level impossible. There are cases where the Layout choice must be done within the X monad. In this cases the composition of layout descriptions will loose all the choice information. Since the description method is presently used to match a given layout, composition at the class level breaks the current design. There are 2 solution: 1. change the type signature of description to layout a -> X String 2. using something else to match layouts. The second one seems the worse in terms of coding effort.
