Enum syntax - extra comma allowed at end?
<p>Was surprised to see that a C# Enum definition seems to allow an extra comma at the end (at least in VS2010). </p>

<p>e.g. : </p>

<pre><code>public enum EnumTest1
{
    Abc,
    Def,
}
</code></pre>

<p>i.e. there is a comma at the end of "Def". 
Just wondering if this is allowed by design, or is an oversight. 
(This might be good to know, because if it is a bug, there may be no guarantees that code like the above will compile in future versions of C#).</p>
