I have heard just a little bit about the language Crystal every so often, probably since it was first mentioned on /r/programming. From what I know, it's Ruby-like syntax but with a static type system, which seems like a big benefit to me.

I written just a little bit of Ruby, so the syntax isn't very familiar to me, and I haven't bothered trying Crystal out, but I'm curious to know what kinds of things people do with it.

So, my questions are: Do you have any experience with Crystal? If so, what have you used it for? Was it a professional or recreational project? How did you like it? What about it stood out to you compared to your experiences with other languages?

Thanks!
