Ignore a property while using jquery $.extend()?
<p>Is there an efficient way to clone an object yet leave out specified properties? Ideally without rewriting the $.extend function?</p>

<pre><code>var object = {
  "foo": "bar"
  , "bim": Array [1000]
};

// extend the object except for the bim property
var clone = $.extend({}, object, "bim");
// = { "foo":"bar" }
</code></pre>

<p>My goal is to save resources by not copying something I'm not going to use.</p>
