Comment SentencesSee https://golang.org/doc/effective_go.html#commentary. Comments documenting declarations should be full sentences, even if that seems a little redundant. This approach makes them format well when extracted into godoc documentation. Comments should begin with the name of the thing being described and end in a period:
記錄聲明的注釋應該是完整的句子，即使這看起來有點多余。這種方法使它們在提取到 godoc 文檔時格式良好。注釋應以所述物品的名稱開始，並以句號結束:

正是如此，golint 才會拋出這條警告，聲明你寫的代碼不符合規范。
符合規范的修改：
在方法調用中，能看到注釋信息：
