禁止在非严格上下文中使用 with 语句。

¥Disallow with statements in non-strict contexts.

with 语句可能会出现问题，因为它会将对象的成员添加到当前范围，从而无法判断块内的变量实际上指的是什么。

¥The with statement is potentially problematic because it adds members of an object to the current scope, making it impossible to tell what a variable inside the block actually refers to.
