I hope 'it' means unsafePerformIO, not Haskell :) I agree. Without unsafePerformIO Haskell gives me many guarantees for free. With unsafePerformIO, they are no longer for free, I have to think, prove, etc. When I mistakenly give a pure function interface to an unpure "function", it can affect my program in most unexpected places.
