它使用这些信息来确保只对位于同一代码块中相同范围级别的赋值语句执行对齐。
It USES this information to ensure that it aligns only those assignment statements at the same scoping level in the same block of code.
All right? So if I called sqrt alone, that return test value is done, but in this case I bound it to test, so I can go look at test, and there it is.
执行完返回值语句,但是在这里我将把它赋值给,所以当我看test的值的时候就是返回的值。
