input of type String -> String

I asked recently whether reading from file can be made of type String -> String. I thought "If Haskell is non-functional, probably, this would be possible, and I would try this in certain small example. Otherwise, this is impossible, and I would be satisfied with readFile name >>= putStr " Thanks to people who explained me that the former case is impossible. So, Haskell is more functional than I thought. ----------------- Serge Mechveliani mechvel@botik.ru
