> But why are they implemented in the IO monad? because they need its features. but i/o may be implemented w/o IORefs. so sequence was: searching for a was to make i/o in Haskell (you can read about this in "History of Haskell"), finding monads as general approach to implement side-effects, naming one of monads used to interact with external world as IO, adding "variables" support to list of operations of this monad -- Best regards, Bulat mailto:[EMAIL PROTECTED] _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
