As a general rule you should never convert between String and bytestring. You can read bytestrings from files, or write literals using "pack" or the -XOverloadedStrings extension Converting between lazy and strict bytestrings is a representation change, and changes complexity - so be aware of what you're doing. You can do this via fromChunks or concat . toChunks. -- Don _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
