I tend to think of Haskell as an eccentric professor.

Sometimes it's brilliant and what it's developed lets you do things that would be much harder in other ways.

Sometimes it just thinks it's clever, like the guy who uses long words and makes convoluted arguments about technicalities that no-one else can understand to look impressive, except that then someone who actually knows what they're talking about walks into the room and explains the same idea so clearly and simply that everyone is left wondering what all the fuss was about.
