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
