The Other Prelude
Call for Contribution
This fun project, called "The Other Prelude", and is a creative reconstruction of the standard Prelude. By disregarding history and compatibility, we get a clean sheet.
The principal is to make the names very readable for both beginners and category theorists (if any).
- The prelude should not contain any "projection" functions (like
snd. They go to the Extension module.
- Should alphanumeric names be preferred over symbols when defining a class?
TheOtherPrelude- Minimalistic module.
TheOtherPrelude.Extension- Convenient definitions.
Currently, the code is in Wiki form. If people do agree that the collaborative decisions begot something pretty, we'll have a group of files in darcs.haskell.org some time.
The imaginery Prelude as it stands,
import Prelude () -- hide everything -- the idea is to remove 'fmap' -- and map :: (a -> b) -> [a] -> [b] to be a special case class Functor f where map :: (a -> b) -> f a -> f b -- should the Functor hierarchy proposal be adopted? class Monad m where (>>=) :: m a -> (a -> m b) -> m b (>>) :: m a -> m b -> m b return :: a -> m a fail :: String -> m a
How to use it, as it stands,
import Prelude () -- hide everything import TheOtherPrelude -- get everything import qualified TheOtherPrelude.Monad as M -- standard convention
