禁止 then 属性。

¥Disallow then property.

当将具有 then 方法的对象（thenable 对象）与 await 表达式或动态导入组合时，需要小心谨慎。这些语法将对象的 then 方法解释为用于解决或拒绝承诺，这可能会导致意外行为或错误。

¥When combining objects with a then method (thenable objects) with await expressions or dynamic imports, caution is necessary. These syntaxes interpret the object’s then method as intended for the resolution or rejection of a promise, which can lead to unexpected behavior or errors.
