When a macroexpansion tries to evaluate an unbound variable, as in the following,<br><br>
(ps (macrolet ((blah () x))<br>
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; (blah)))<br><br>the resulting error message is unhelpful: &quot;Attempt to take the car of &quot;Unbound Value&quot; which is not listp.&quot;<br><br>Could it say &quot;Attempt to take the value of the unbound variable X&quot; instead?
