I'm not a fan of significant whitespace in programming but I was happy to overlook this with Nim because of all the other language awesomeness. I don't think indentation syntax is a show-stopper when trying to learn a new language, I don't think people will ignore Nim's flexibility and elegance just because they have to indent their code (or the other way round, in case of curly braces).
Having said that, @Libman's idea is great. Programming languages should allow programmers to express themselves in the way that the programmers see best, not try to force them to adapt to the language. Nim, so far, has been very good at this and allowing coders to use multiple statement delimiters, i.e. skins, would go a long way towards that. I wish I had the knowledge to do this myself.
