上下文形参通过作用域内的上下文形参和接收者隐式解析。

示例：

  interface Logger { fun log(message: String) }

  context(logger: Logger)
  fun logWithTime(message: String) {
      logger.log("${LocalDateTime.now()}: $message")
  }

  fun saveUser(user: User, logger: Logger) {
      context(logger) {
          logWithTime("saving user ${user.id}")
      }
  }

该快速修复可以将隐式上下文实参转换为显式上下文实参：

  fun saveUser(user: User, logger: Logger) {
        logWithTime("saving user ${user.id}", logger = logger)
  }
