My current workaround is to make truly-the a macro.<br>

`(the ,type ,value))<br>
TRULY-THE<br>

Load 1 ASDF system:<br>
screamer<br>

My thoughts would be to remove the special form longer term. Even though we have special-purpose compilation support for it, I don't see benefits in keeping it around. It's supposed to allow increased performance for compiled programs. So, upon removal, we probably need to verify that the performance degradation is small enough.</div>
