The unicode correspondance? I would start typing C-x 8 RET double TAB and not find it in the list. So I would have to launch clisp, C-- slime RET clisp RET wait for it to boot then type: (lschar :name "RIGHT_ARROW") RET the search for double, and not find it, then copy and paste it from your message, (char-name #\⇒) obtain the character name as "RIGHTWARDS_DOUBLE_ARROW", then type C-x 8 RET rightward double arrow RET which, even if I had know it from the start, is still much more difficult to type than just =>. > Ironically the page where this is documented > https://downloads.haskell.org/~ghc/7.6.3/docs/html/users_guide/syntax-extns.html > the last two dont work (show) because the html is charset=ISO-8859-1 :-) > I guess unicode is a moving target... > > 5.
