For clarity, Susie's code has turned from something sync like:

```
function getFoo(): Foo
{
  $resultOne = sendHttpRequest('one');
  $resultTwo = sendHttpRequest('two');

  return new Foo($resultOne, $resultTwo);
}
```

into something async like:

```
function getFoo(): Foo
{
  $results = await Async\all([
    spawn sendHttpRequest('one'),
    spawn sendHttpRequest('two')
  ]);

  return new Foo($results[0], $results[1]);
}

```

Is that correct Rowan?

Yes, this was precisely the point of my &quot;SDK Susie&quot; user story: S=
usie is not interested in maintaining multiple libraries for different part=
s of the community, she just wants her API to be usable by as many PHP deve=
lopers as possible. <br>
<br>
If she can&#39;t use async I/O without breaking Legacy Les&#39;s applicatio=
n, she will simply not use it. Async Alice might write her own code for the=
 API calls she needs, but won&#39;t want to maintain a fork of the entire l=
ibrary. Beginner Bob will use the official library and not get any async be=
nefits. <br>
<br>
This is basically the situation we already have, with Async Alice using Swo=
ole or ReactPHP.<br>
