Is there a case for a String.IsNullOrEmpty operator?
<p><code>String.IsNullOrEmpty()</code> appears to be an extremely well used method and I find myself wishing there were some shorthand for it. Something like <code>???</code> as it would be used in a similar context to the null coalesce operator but be extended to test for empty as well as null strings. I.e.</p>

<pre><code> string text = something.SomeText ??? "Not provided";
</code></pre>

<p>What would be your opinions on this? Would it unnecessarily bloat the language? Would it open the floodgates for other mid-level operations to be granted such deep integration with the compiler? Or would it be a useful addition for the language.</p>
