I think you're right, and that's a strong reason to come up with an update to the Haskell Report. Include in it, at least:
-- Big-ticket items 0. Monoid 1. Foldable, Traversable 2. Applicative 3. Applicative => Monad -- side notes 4. inits = map reverse . scanl (flip (:)) [] -- efficiency—not optimal but not hilariously bad 5. unwords = intercalate " " -- increased, more intuitive laziness On Tue, Nov 18, 2014 at 11:44 AM, Richard Eisenberg <e...@cis.upenn.edu> wrote: > I support this direction.
