Newbie question: why does the following give "Not in scope 'c'" for the last line? string :: Parsec.Parser String string = do c <- Parsec.letter do cs <- string return c:cs Parsec.<|> return [c] (This is copied more or less rote from http://legacy.cs.uu.nl/daan/download/parsec/parsec.html , so I'm guessing there's some sort of command-line option I'm missing?)
