type Comment struct 
    name string       // 该指针为空, 初始化时才能设置为空;
    flags *FlagSet
    PostRun func(cmd *Comment, args []string)    //结构中的抽象方法
 


c := &Comment"name",nil, func(cmd *Comment, args []string) 
    strings.Join(args," ")



func (c *Comment) Flag() *FlagSet
    if c.flags == nil
        c.flags = NewFlagSet(c.name, ContinueOnError)
    
    return c.flags
