Go语言提供了内置的支持运行时反射的实现,并且借助于reflect包允许程序操作具有任意类型的对象。Golang中的reflect.Append()函数用于将x值附加到切片s中。要使用此函数,需要在程序中导入reflect包。 语法: funcAppend(s Value,x...Value)Value Go Copy
补充信息:Go中没有引用传递 官方说明: In a function call, the function value and arguments are evaluated in the usual order. After they are evaluated, the parameters of the call are passed by value to the function and the called function begins execution. ...

2023年5月25号,知名Go技术专家,WA语言[1]联合发起人,多本技术书籍的合著者柴大[2],遇到一个append忘记写要添加的元素,只写了第一个参数(要追加的切片)的问题,可以编译通过,但大概率不是开发者本意。目前go vet缺失这样的检测项,柴大知道我对Go源码一直充满热枕,建议尝试实现。
