On the other hand, IO is lazy in the values it produces. Going with the IO a = State RealWorld a fiction, IO is state-strict but value-lazy. The side-effects affect the state, hence are performed, the values are only evaluated to the extent required to determine the state. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
