Haskell itself may be the greatest troll of all time. I'm dense, and it takes me a while to "get it". But Haskell may be such an awesome troll that even the people who implemented the language may not be in on the joke yet either.
Normally we look down on trolls. But just maybe, a troll can be so perfect that it can be admired as a work of art. Haskell may well be that instance of trolling elevated to an art.
