<h2>MUST-BE-EQUAL</h2>attach code for execution
<pre>Major Section: <a href="PROGRAMMING.html">PROGRAMMING</a>
</pre><p>
<p>
The form <code>(must-be-equal logic exec)</code> evaluates to <code>logic</code> in the ACL2
logic but evaluates to <code>exec</code> in raw Lisp. The point is to be able to
write one definition to reason about logically but another for evaluation.
Please see <a href="MBE.html">mbe</a> and see <a href="MBT.html">mbt</a> for appropriate macros to use, rather than
calling <code>must-be-equal</code> directly, since it is easy to commute the arguments
of <code>must-be-equal</code> by accident.<p>
The guard for <code>(must-be-equal x y)</code> is <code>(equal x y)</code>.
