You have a point there. If split over several lines, I'd recommend each line indented further than the previous to indicate nesting: newtype MyCoolMonad = MyCoolMonad (FirstTransformer (SecondTransformer (ThirdTransformer Whatever))) But I wouldn't really prefer that over having it on one line. > > > deriving (Functor, Monad, > > FirstClass, SecondClass, ThirdClass, SomeOtherClass) > > A lot of unnecessary information distracting the reader.

IMO, having the deriving clause on the same line (unless it's a very short one) obscures the code and makes it *much* harder to read. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
