Issue 129: ClassLayout.description type signature is wrong http://code.google.com/p/xmonad/issues/detail?id=129 Comment #1 by SpencerJanssen:

There are cases where the Layout choice must be done within the X monad.

I challenge this assertion. I've sketched a design for PerWorkspace that can determine the description purely. I also note that the 'Choose' layout in the core allows for dynamic selection of layout, and it gets by with a pure description. Please demonstrate some layouts that truly need description :: X String. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
