CoffeScript'esque language for Objective-C?

Question

Seeing what has been done for Java with Xtend and Mirah I can't help but think someone must be playing around with something similar for Objective-C or even C and C++ for that matter.

After some searching I've come up with nil. Is anyone aware of a CoffeeScript like Objective-C implementation?

Update: Good input so far from the two that have submitted answers, however wouldn't it be superior (realizing that that's a little subjective) to have an intermediate language that compiled directly to Obj-C precisely as per how CoffeScript works? Now, I'm not asking for CoffeeScript mind you, but rather some language that doesn't compile directly, but rather gives you a more readable top layer syntactically a la Xtend.

Answer 1

Yes: Eero, which provides a somewhat Python-like syntax for Objective-C, implemented using a modified version of clang. (I haven't tried using it, though, so I can't comment on how useful it is!)

Answer 2

MacRuby and RubyMotion let you code Mac and iOS applications (respectively) in pure Ruby. CoffeeScript is very Ruby-inspired, so if you enjoy that language, i think you'll feel at home with Ruby :)

Also, it is my understanding that both MacRuby and RubyMotion integrate nicely with the native environment; they don't run on a separate Ruby VM on top of Mac/iOS, so there is no big performance penalty and the native things are not that far away. So in that sense i think they are more similar in sipirt to Mirah for the JVM than to JRuby or Jython for example.
