I use it when I need a local loop expression, maybe once every couple of months. A real world example from xmonad,

f = fix $ \again -> do more <- checkMaskEvent d enterWindowMask ev when more again

That is, keep sucking up X events till there's no 'more'.

My God... that's almost as cute as the first thing!
