dereference的优先级

*的优先级是低于属性.的优先级的

*地址 = object

举例：defs.go

package defs

type Matter struct {
    Question string
    Answers  []string
}

type Matters []Matter

parse.go

func getObject(c string) *defs.Matters {
    matters := &defs.Matters{}
    ms := strings.Split(c, "\n\n")
    for _, m := range ms {
        matter := &defs.Matter{}
        mt := strings.Split(m, "\n")
        (*matter).Question = mt[0] //等价于matter.Question = mt[0]，但是*matter.Question = mt[0]就会报错
        (*matter).Answers = append((*matter).Answers, mt[1:]...) //slice... []展开符 = string
        *matters = append(*matters, *matter)
    }
    return matters
}
