Yeah, I'm aware that the whole point of it is the needless complexity of the latter solutions—still, you have to know Haskell to understand exactly why the latter solutions are so ridiculous (beyond merely gawking at them unappreciatively) and you have to understand Haskell even better to actually come up with the penultimately-contrived solutions.

I'd like to be able to tell those jokes without it being like making sounds in a foreign language—that's what I mean by "knowing" Haskell. You can't speak a language until you can make a witty retort in it ;)
