Error when parsing eval in .d.ts

[liuxingbaoyu]

This should not throw an error.

// @filename: /a.d.ts
declare global {
    export namespace ns {
        export function eval(): void;
        export function arguments(): void;
    }
}

declare function eval(): void;
declare function arguments(): void;

export {}

I discovered it while updating our typescript testing repo.

Oh! This is not a bug, this is a change introduced in ts 5.5.
