declaration - 在 x++ 中声明后真的需要分号吗？

Question

正如书中所说 Microsoft Dynamics AX 2009 编程:入门 需要在 x++ 中的声明后放置分号:

The extra semicolon after the variable declaration is mandatory as long as the first line of code is not a keyword. The semicolon tells the compiler that variable declarations have come to an end. You cannot declare new variables after this semicolon.

(直接从书中复制，不变，如果需要我会删除它)

但是，当我删除分号并运行作业时，绝对没有错误或问题:

static void Job1(Args _args)
{
    str string1 = "STACKOVERFLOW";
    ;
    print string1;
    pause;
}

就像

static void Job2(Args _args)
{
     str string1 = "STACKOVERFLOW";

     print string1;
     pause;
}

真的需要吗？我应该习惯使用它吗？

它的解释相当优雅here .
一个关键引述[强调我的]:

"The reason you need that extra semicolon is because the compiler can’t always see where the variable declarations end. If you don’t help a little, it will make a guess. And it’s not very good at guessing."

While the compiler is analyzing the code it checks if the first word on a line matches the name of a type (AOT object). If it’s a type name the compiler treats the line as a variable declaration. In this case a variable name should be next.
