Scope of comma delimeted variables
<p>It occurred to me, that I have no idea what the scope of </p>

<pre><code>var foo='bar', 
baz = 'bar';
</code></pre>

<p>is.</p>

<p>Obviously foo is locally scoped, but is the var keyword necessary on baz to scope it locally, or is my example already locally scoped?</p>
