The objective-c with ARC support really enjoys some advantages script programing languages enjoy. Apple added many syntax sugar such as `@[]` to build array and `@{}` to build dictionary, which makes it easy to write.

So I am not surprised someone is trying to use it as a so-called shell script. The cocoa frameworks really contains a lot of convenient API (ex. when it comes to python, you have to install PIL or something else to process images). But on the other hand the objective-c shell scripting can not be used on platform other than OSX. That is a disadvantage.
