I'm not sure how representative xmonad is of GUI applications. Raw X11 is
likely very different from wxHaskell, and xmonad isn't really interactive in
the same way that GUIs are.

Regardless, XMonad.StackSet is a good study in how to separate an application's
model into a separately testable, purely functional module.

PS: It's true, there isn't a single IORef in xmonad's core
