In clojure:

    (-> someGameState
      handleCollisions 
      handleShake
      handlePolice
      ;; ...
      renderGameState)

    ;; ->> would work as well in this example cause it's both first and last argument

But this code is only pretending to be functional, because in practice every function can modify everything. So looking at this I have no idea where the particles were created - I have to look at every function anyway.
