I'd use
[ c | (xs,w) <- l, c <- (show xs) ++ " " ++ w ++ "\n" ]
instead -- after all, list comprehensions provide a much nicer syntax for map, filter and concat.
Or, if you hate append as much as I do: [ c | (xs,w) <- l, cs <- [show xs, " ", w, "\n"], c <- cs ] If you're hard-core, you can turn show into shows and delete a comma... (OK, it's terribly silly in this example, but I do use list comprehensions in this way to avoid concat-ing an already-appended-together list.) -Jan-Willem Maessen
