I have a better polyfill now, it won't delete & restore the prototype @ljharb

Still, DONT USE IT IN YOUR PRODUCT

```javascript
Array.prototype.then = async function (resolve, reject) {
    class NonThenableArray extends Array {}
    NonThenableArray.prototype.then = 0
    NonThenableArray.prototype[Symbol.species] = NonThenableArray
    const result = new NonThenableArray()
    // This won't make promises parallel
    for (const p of this) {
        try { result.push(await p) }
        catch (e) { return reject(e) }
    }
    resolve(result)
}

```
