为什么在我的示例中TypeScript编译器会忽略'noImplicitThis'选项？

Question

Consider the code:

class x {
    public variable: number = 0;
    public x() {
        const c = [];
        c.push({
            xxx () {
                console.log(this.variable);
            }
        });
    }
}

The anonymous function xxx doesn't have access to 'this' of class 'x'. Normally this can only compile if 'this' implicitly has type any. But it does compile .

If I extract my literal object in a separate value, I actually do get a compilation error that I expect.

Is it a compiler bug?

Note: you need to manually enable 'noImplicitThis' in typescript playground because apparently options are not sharable.
