我正在嘗試像這樣導(dǎo)出一個常量：package logconst (    FATAL = iota // fatal errors    ERROR = iota // errors might happend    DEBUG = iota // debug mode) // const for logging levels但我收到 golint 錯誤：exported const FATAL should have comment  (or a comment on this block) or be unexported (golint)沒錯，我后來在訪問 log.FATAL 等時遇到了錯誤。
