Well, Unit Tests also came from it (SUnit was the first Unit Test framework). Which is unsurprising, as refactoring without unit tests is quite daunting. But JUnit did make them mainstream, and so did Eclipse' refactorings.

Interestingly, refactoring usually works quite well for functional Haskell code without tests just relying on the types. (Of course the types won't help you in more imperative sections of your code, i.e. it's hard to guarantee a specific order of actions in the IO Monad with types only.)

    Yes. But the pure part of your program tends to be bigger in Haskell than in Java.

      And the type system (and compiler) help you know what's pure and what's not.
