难倒这个，肯定有一种优雅的方式来做到这一点，但不确定是什么。

我想要类似的东西：

let x = 5;

const p = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve();
  }, 2000);
}).then(() => {
  console.log(x);
});

x = 3;
// Print out 5 after 2 seconds.

基本上，给定与上述类似的设置，是否有办法打印输出，'5'而不管x在异步超时期间的值是否更改？就我而言，这将是很难简单地通过x在resolve()。

当我有以下最小重现代码时：

启动.py

from __future__ import annotations

import a

a.py

from __future__ import annotations

from typing import Text

import b

Foo = Text

b.py

from __future__ import annotations

import a

FooType = a.Foo

我收到以下错误：
