说明：  编程语言已经非常多，偏性能敏感的编译型语言有 C、C++、Java、C#、Delphi和Objective-C 等，偏快速业务开发的动态解析型语言有PHP、Python、Perl、Ruby、JavaScript和Lua等，面向特 定领域的语言有Erlang、R和MATLAB等，那么我们为什么需要 Go这样一门新语言呢？
(There are a lot of programming languages. The compiled languages with biased performance are C, C++, Java, C#, Delphi and Objective-C. The dynamic parsing languages such as PHP, Python, Perl, Ruby, JavaScript and Lua, etc., are for special purpose. There are Erlang, R and MATLAB in the domain language. Then why do we need such a new language such as Go?)
