Yield Return Many?
<p>I find myself foreach-ing over IEnumerables a lot just so that I can return each result. Is there a way to compress something like this</p>

<pre><code>foreach (var subSelector in subSelectors)
{
    foreach (var node in FindSingle(context, subSelector))
        yield return node;
} 
</code></pre>

<p>To remove the inner foreach?</p>
