Prelude> :m + System.IO.Unsafe Prelude System.IO.Unsafe> :t unsafePerformIO unsafePerformIO :: IO a -> a Prelude System.IO.Unsafe> :t unsafeInterleaveIO unsafeInterleaveIO :: IO a -> IO a The former lets you cheat by pretending an IO action is a pure function, the latter, which really should be called 'notQuiteAsUnsafeInterleaveIO', just makes a strict IO action lazier, deferring it to when the result is demanded. -k -- If I haven't seen further, it is by standing in the footprints of giants _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
