“在这里注意到 goto again 语句，结合上下文可得若正在进行扩容，就会不断地进行迁移。待迁移完毕后才会开始进行下一次的扩容动作”这句话是不是有点问题呀？

    if !h.growing() && (overLoadFactor(h.count+1, h.B) || tooManyOverflowBuckets(h.noverflow, h.B)) {
        hashGrow(t, h)
        goto again // Growing the table invalidates everything, so try again
    }

这里goto again不应该是用来重复一遍扩容前的操作吗？如果已经再扩容了，根本就不会走到这段代码的呀
