That looks interesting. However, i'm not really into language-design and compilers and the first commit is from April while the project has only two contributors. Apart from the absence of a standard-library, I couldn't find anything like "attention, this is in beta". Don't get me wrong, I just would be surprised if this really was a stable language developed in under three months.

(Something I was wondering about is that it says "Contains orange standard library stuff" in https://github.com/orange-lang/orange/blob/master/lib/libor/... and "At the moment, Orange has no standard library" in https://github.com/orange-lang/orange/blob/master/README.md at the same time.)

Edit: I definitely was too fast. https://github.com/orange-lang/orange/tree/master/lib/libor doesn't contain any code.
