goLang。 调用“ .Front（）”以获取字符串列表。 但是返回错误，提示字符串列表没有Front方法

I have code like this

t := strings.FieldsFunc(value, extract_word)
        fmt.Println("t:", len(t),t)
        m := make(map[string]int)
    for word := t.Front(); word != nil; word=word.Next(){
            m[word]++   
    }

and it gets this error

t.Front undefined (type []string has no field or method Front)

I know list has Front() method. http://golang.org/pkg/container/list/ but why it complains here? so confused, need help. thank you!
