Except in Haskell, it's not just some pet bit of code by the authors. It's a shared abstraction with well understood laws and theoretical underpinning. What people call "clever" code in mainstream programming is not in any way similar to the Haskell being referred to. Luckily in the Haskell world, we don't ascribe negative attributes like "cleverness" to code that isn't outsider-friendly. We gain a lot by not requiring that all our code is understandable by a mainstream programmer.
