Experientially, we see it a lot in #xmonad from beginners combining stuff
together with a certain amont of cargo-culting (being beginners and usually
quite unfamiliar with Haskell).
I've been moving toward using ($) to separate logical "phrases" and (.)
within the phrases, to make it easier to see which things go with which.
Since layoutHook is rather agglutinative, this helps a lot.
