如何有效地链接字符串 - How to efficiently concatenate strings

问题：

In Go, a string is a primitive type, which means it is read-only, and every manipulation of it will create a new string. 在Go中， string是基本类型，这意味着它是只读的，而且对它的每次操做都将建立一个新字符串。

So if I want to concatenate strings many times without knowing the length of the resulting string, what's the best way to do it? 所以，若是我想在不知道结果字符串长度的状况下屡次链接字符串，那么最好的方法是什么？

The naive way would be: 天真的方式是：

s := ""
for i := 0; i < 1000; i++ {
    s += getShortStringFromSomewhere()
}
return s

but that does not seem very efficient. 但这彷佛不是颇有效。
