英文:
Simultaneous assignment in Go
问题
我正在学习Go语言，有一件事我不太明白，为什么这门语言的创造者支持同时赋值？这样很容易出错，比如 a, b = a, b 而不是 a, b = b, a，我希望能得到一些好的解释，提前感谢。
英文:
I'm learning Go and can't understand one thing, why creators of this language do support simultaneous assignment? It is very easy to make mistakes like a, b = a, b and not a, b = b, a, as I would want, thanks in advance for any good explanations.

如果没有同时赋值的功能，那么你就需要采取其他方法。另一种替代方案可能是这样的：
tmp = a
a = b
b = tmp
这样做容易出错。
英文:
> It is very easy to make mistakes like a, b = a, b and not a, b = b, a,
If simultaneous assignment were not available then you would have to do something else instead. An alternative approach might look something like this:
tmp = a
a = b
b = tmp
That's much easier to get wrong.

你还能以什么方式获取函数的第二、第三、第四，以及更多的返回值呢？
英文:
How else would you get access to the second, third, fourth, … return value of a function?
