### Cancellation propagation attempt
This code does automatic signal propagation using `AsyncLocalStorage`, it's pretty short and its purpose is to see if this API is useful, useless or just foot-gunny.
For example this lets you do:
```js
import { withCancel, signal } from './index.js';
const ac = new AbortController();
setTimeout(() => ac.abort(), 10);
let count = 0;
await withCancel(async () => { // wrap with an IIFE if you don't have TLA enabled
try {
await timersPromises.setTimeout(60000, 0, { signal: signal() });
} catch (e) {
count++;
}
}, { signal: ac.signal });
strictEqual(count, 1);
```
This means that instead of passing `signal` everywhere you can just call the `signal()` function and access the abort signal from context.
