Talk:Functor hierarchy proposal

Um, it would be good if it was something like:

class (Idiom f) => Monad f where
  fmap f m = m >>= return . f -- or ap . return ?
  ap mf mv = mf >>= \f -> mv >>= \v -> return $ f v
  (>>=) :: f a -> (a -> f b) -> f b

Or am I missing the point?

You can't put defaults for one class in another. Though that could be another proposal. —Ashley Y 21:02, 29 January 2006 (UTC)
