re every iteration of the loop. If it is <code class="mendoza-code">nil</code> or <code class="mendoza-code">false</code>,
the <code class="mendoza-code">while</code> loop ends and evaluates to <code class="mendoza-code">nil</code>. Otherwise, the rest of
the parameters will be evaluated sequentially and then the program will return
to the beginning of the loop.
