I had a quick look at the language and checked about my two pet pieves. What does the code look like when handling JSON data? (that is when I slammed the door on Golang) What does the code look like when starting an external process, supplying stdin, args and capturing return code, stdout, and stderr? (that is when I slammed the door on lua). Well, I must say that crystal-lang manages to dodge the bullet twice. It handles both situations quite elegantly. So, yes, I am interested.
