Re: [Haskell-cafe] How efficient is read?

data Something = Something Int (Maybe String) deriving Show {-! derive : Parse !-}

There is nothing in the generated parser to look for parens around the Maybe in case it is a (Just string).

Sorry, that will be my fault. I contributed the rules for deriving Parse to DrIFT. I am on holiday right now, but will try to take a look shortly. Regards, Malcolm
