Once those tasks are done, the resulting executable has a list of symbols it plans to look up from libraries it will load at runtime.

在完成这些任务之后，生成的可执行文件会拥有一个列表，该列表列出了计划从运行期将加载的程序库中找出的那些符号。

We've tended to steer clear of heavily symbolic libraries and using symbols for method names, but I think this is an important feature of the language, which like any feature is possible to over-use.

我们其实也在避免使用重量级的符号库，避免用符号来做方法名，但我觉得这是Scala的一个很重要的特性，也跟其他特性一样，都有可能被过度使用。
