Just noticed a small thing in which python does a bit better than haskell: $ ghci let (fine, fine) = (1,2) Prelude> (fine, fine) (1,2) Prelude> In case its not apparent, the fi in the first fine is a ligature. Python just barfs: >>> fine = 1 File "<stdin>", line 1 fine = 1 ^ SyntaxError: invalid syntax >>> The point of that example is to show that unicode gives all kind of "Aaah! Gotcha!!" opportunities that just dont exist in the old world. Python may have got this one right but there are surely dozens of others. On the other hand I see more eagerness for unicode source-text there eg. https://github.com/i-tu/Hasklig http://www.haskell.org/ghc/docs/latest/html/users_guide/syntax-extns.html#unicode-syntax http://www.haskell.org/haskellwiki/Unicode-symbols http://hackage.haskell.org/package/base-unicode-symbols Some music 𝄞 𝄢 ♭ 𝄱 to appease the utf-8 gods -- https://mail.python.org/mailman/listinfo/python-list
