Re: [Haskell-cafe] Unicode Haskell source -- Yippie!

It's disgusting. Отправлено с iPhone

I'm mighty pleased to note that the following is valid Haskell code!

Do others find this useful/appealing? Any possibilities on making the commented out parts work?

[Pragmatics about typing this at the same speed and facility as we do with Ascii is a separate and (IMHO) solvable problem though its not the case at the moment]

-------------------- import qualified Data.Set as Set -- Experimenting with Unicode in Haskell source

-- Numbers x ≠ y = x /= y x ≤ y = x <= y x ≥ y = x >= y x ÷ y = divMod x y x ⇑ y = x ^ y

x × y = x * y -- readability hmmm !!! π = pi

-- ⌊ x = floor x -- ⌈ x = ceiling x

-- Lists xs ⤚ ys = xs ++ ys

-- Bools x ∧ y = x && y x ∨ y = y || y -- ¬x = not x

-- Sets

x ∈ s = x `Set.member` s -- or keep ∈ for list elem? s ∪ t = s `Set.union` t s ∩ t = s `Set.intersection` t s ⊆ t = s `Set.isSubsetOf` t s ⊂ t = s `Set.isProperSubsetOf` t s ⊈ t = not (s `Set.isSubsetOf` t) -- ∅ = Set.null
