LLVM 4.0 Compiler

• Default @synthesize: automatically synthesizes an @property when unimplemented

• Objective-C literals: create literals for NSArray, NSDictionary, and NSNumber, just the same as the literals for NSString

• Objective-C container subscripting: use '[]' syntax to access containers such as NSArray and NSDictionary

变得越来越像CPP了。。。

看来CPP还是很经典的么。。。

不过cpp貌似不允许在[]里填字符串，恩恩，应该说转变的更像python
