The Crystal Programming Language(crystal-lang.org)

This looks like a cool language, it's essentially a native ruby. I've only played around with the online tool and written some simple ruby and it just works. Seems like the main thing that makes it different is all the type stuff needed to make it. The nice thing is that for the most part, the types are inferred, so you don't have to change the way you write code too much in order to accommodate it.
