computedFrom a signal?
<p>is it possible to base a @computedFrom on a signal? something like:</p>

<pre><code>@computedFrom({signals: ["mySignalKey"]})
</code></pre>

<p>or</p>

<pre><code>@signaledFrom("mySignalKey1", "mySignalKey2")
</code></pre>

<p>It would help in a use case where I have a property whose value is computed from a property on each of many objects in an array of objects.</p>

<p>(Or maybe there is already a better way?)</p>
