### Variadic callbacks
Much like `deferred`, you can receive multiple callback arguments by passing the `variadic` option to promisify. This also works with `promisify.methods` and `promisify.all`.
```js
const { promisify } = require('promise-callbacks');
function respondWithDelay(done) {
setTimeout(() => done(null, 3, 2, 1, 4), 2000);
}
const respondWithDelayPromised = promisify(respondWithDelay, {variadic: true});
async function foo() {
console.log(await respondWithDelayPromised());
// => [3, 2, 1, 4]
}
```
