We see so many language critiques or preferences where the visuals seem to have been a main problem. "line noise" "sigils!!!" "too many parentheses" "unicode!!!". Which to me denote languages judged long before being looked at with any care. Should this be a fundamental lesson for language designers? Should languages come with a converter to switch back and forth between the "calm, proper english version" and the "compact, expert mode" visual? (Without mentioning the translated programming languages like BASIC in french and such things which were discussed on HN not long ago.)
