It is not this simple.  There is not a simple variable that tracks which  
window is focused.  The focus is implicit in the way the StackSet data  
structure is organized.  That's why this ticket has languished so long ---  
implementing it would really require a quite invasive restructuring of  
xmonad's core data structures.
