Issue 129: ClassLayout.description type signature is wrong http://code.google.com/p/xmonad/issues/detail?id=129 Comment #3 by andrea.rossato: while waiting for Spencer's proof, in either directions (time is on my side... ;), I'm attaching the class and the instance as I'm designing them. the file does not even compile (see comments). Just to have something we can discuss.
