> Actually a super-power of Haskell is how easy it is to refactor from "quick n dirty" to "reasonable quality" without introducing defects. I call haskell "the language of maintainable spaghetti" in this spirit. It really is incredible how types can take 99% of the risk out of refactoring. Indeed while I miss machine refactoring tools from Java, I've seen vanishingly few bugs result from manual refactoring in haskell.
