I don't think you can: the best you can do is minimise it with other monadic functions. The general case you can do something like discard from polyparse: http://hackage.haskell.org/packages/archive/polyparse/latest/doc/html/Text-ParserCombinators-Poly-Base.html#v:discard -- Ivan Lazar Miljenovic ivan.miljeno...@gmail.com IvanMiljenovic.wordpress.com _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
