[Haskell-cafe] Network of GUI Controls - using MonadFix?

[Günther Schmidt]

Hello list,

let's say I would like to create 4 buttons where any one button can 
respond to a click and notify every other button.
Ie. where the 1st button is wired with the 2nd, the 2nd with the 3rd ... 
and the 4th button with the 1st.

In short I would like these buttons to be connected as in a cyclic list.

Is that something that MonadFix is meant to be used for?
