Thanks, I see it now! Laziness is not there! But still... Identity is a bit special monad. What other monads need full laziness in sequence? As far as I know IO is strict. What about lazy/strict state monad? Initially I spotted this possible optimization in context of monadic parser. I am not really sure if I need this property there or not. How do I prove this to myself? Thanks to others who responded. -- Gracjan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
