The Nu programming language
programming.nu
programming.nu
The readme there gives also a better introduction to the goals and design decisions of the language.
Basic design:
* Lisp-like.
* Native calls are directly possible from within the language, so you can easily call C code.
* Uses the ObjC runtime.
Example of a Cocoa application: https://github.com/timburks/nu/blob/master/examples/RandomAp...
The last update was September 2, 2011 with the release of Nu 2.0.1.
On GitHub, the last commit was 14 days ago.
Great stuff.
