Georg made the point that if a type is an instance of Show, then it should also be an instance of Read, and read . show == id I'd like to repeat my earlier point that it would be better if the user of the type can decide whether he wants some predefined Show/Read instances or roll his own. http://www.haskell.org/pipermail/libraries/2005-March/003496.html Best regards, -- -- Johannes Waldmann -- Tel/Fax (0341) 3076 6479/80 -- ---- http://www.imn.htwk-leipzig.de/~waldmann/ -------
