<p>Suppose that a class <code class="code"><my-class></code> is defined using <code class="code">define-class</code>
|
||
|
|
(see <a class="pxref" href="Class-Definition.html">define-class</a>), with slots that have
|
||
|
|
accessor functions, and that an application has created several instances
|
||
|
|
of <code class="code"><my-class></code> using <code class="code">make</code> (see <a class="pxref" href="Instance-Creation.html">make</a>). What then happens if <code class="code"><my-class></code> is redefined by calling
|
||
|
|
<code class="code">define-class</code> again?
