并行性的难题和生成有效代码所需的优化不适合在单个的编译器构造的课程中讲。

The hard issues of parallelism and the optimizations needed to produce effective code just don't fit into the time available for a single course in compiler construction.

您可以从警告导航到源代码以及可帮助您编写更有效代码的详细帮助主题。

You can navigate from the warning to your source code and to detailed help topics that help you write more efficient code.

We could certainly implement this much more efficiently by just writing this one line of code, but, again, the key here is to take this step toward decomposing our code into chunks of code.

我们可以写这一行代码,使代码的执行更有效率，但是，这个关键字用来把我们的代码分解,成一段段的。

And that does two things: bug one, it helps catch bugs in your code, and secondly it often converts it into a more efficient sequence of instructions before you actually go off and run it. All right?

这有两点好处：,第一是可以帮助你发现程序中的，第二是把你的代码,在运行之前,转换为更有效率的指令的集合，对不对？
