Determine original name of variable after its passed to a function
<p>I've got a feeling this might not be possible, but I would like to determine the original variable name of a variable which has been passed to a function in javascript. I don't know how to explain it any better than that, so see if this example makes sense.</p>

<pre><code>function getVariableName(unknownVariable){
  return unknownVariable.originalName;
}

getVariableName(foo); //returns string "foo";
getVariableName(bar); //returns string "bar";
</code></pre>

<p>This is for a jquery plugin i'm working on, and i would like to be able to display the name of the variable which is passed to a "debug" function.</p>
