描述

¥Description

禁止从 setter 返回值

¥Disallow returning a value from a setter

虽然从 setter 返回值不会产生错误，但返回的值将被忽略。因此，从 setter 返回值要么是不必要的，要么是可能的错误。

¥While returning a value from a setter does not produce an error, the returned value is being ignored. Therefore, returning a value from a setter is either unnecessary or a possible error.

仅允许返回没有值，因为它是控制流语句。

¥Only returning without a value is allowed, as it’s a control flow statement.
