I've been using Crystal on a mobile checkout application to watch for and parse incoming pricing files. I've been extremely happy with it so far. It is fast, the type system is nice, and I really enjoy the Ruby-like syntax and ease of development. I've also been happy with the developers and the community. The community is supportive and the developers are making good progress on the language and are quite responsive to community feedback. If you like the idea of a fast, compiled, statically-typed, Ruby-like programming language, you can support Crystal development here (NOTE: I'm not affiliated with the Crystal project in any way. I'm just a happy consumer): https://crystal-lang.org/sponsors/ https://crystal-lang.org/sponsors/
