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.
And yeah, as for https://github.com/orange-lang/orange/tree/master/lib/libor, it only contains bootstrap code for the linker at the moment.
