BTW, what does the first "D" in DData stand for? Perhaps "Daan"? I don't like concatenated module names ("D" ++ "Data"). We have hierarchical names to avoid exactly that. It should then perhaps be Data.Daan, similar to module Text.PrettyPrint.HughesPJ -- -- Johannes Waldmann, Tel/Fax: (0341) 3076 6479 / 6480 -- ------ http://www.imn.htwk-leipzig.de/~waldmann/ ---------
