For "real word" experiences, check Crystal lang itself, and lucky, mint-lang, those are not toy stuff.

For friends from China who are interested in Crystal,i create the Github crystal-china org, https://github.com/crystal-china, and I also hold https://crystal-china.org domain name, although there is still no time to build a website.

Let us discuss use Chinese in TG,Discord, and do something together.

The most similar project so far is lucky.

Development by folks come from thoughtbot.

Crytal can disable GC and runtime too.

Of course, same as Nim, you lose access to most of the stdlib.

Hope a lot of people can see this, detailed explanation come from Crystal core developers.

because a lot of beginners complain that Crystal's fiber doesn't work on multiple cores/multiple threads and then give up using it, it's probably not as important as people think.

Even many beginners mistakenly believe that the Crystal language does not support the creation of operating system native Thread， this is a huge misunderstanding for Crystal.

I totally agree with this idea, Crystal core member seems to think less of it from a beginner programmer's perspective.
