I haven't tested myself, but does this work at all? If I am reading it correctly, this is the same as let (foo, rest) = splitAt maxLineLength foo in foo : wrapLine rest In other words, no mention of wrapLine's argument 'line', and a recursive call that will bottom out and be the same as 'undefined' :). GHC would warn you, though, if you used -Wall. That expression should read: let (thisLine, rest) = splitAt maxLineLength line in thisLine : wrapLine rest Cheers, -- Felipe. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
