[xmonad] studying xmonad code as a guideline for gui-code?

[Günther Schmidt]

Hi all,

I'm wondering if studying xmonad code will help me write better gui 
code. I've got some ui-code for wxHaskell, with several drop downs where 
the selection of one drop-down effects the contents of every other 
drop-down. I wrote this with IORefs all over the place and I think this 
problem begs for a zipperish solution.

I have only glimpsed at the xmonad code but I don't remember seeing even 
a single IORef, so I am asking for your opinion: Can studying xmonad 
code provide me with a better solution for my problem?
