<a href="http://d.hatena.ne.jp/sirocco634/20100912#1284300126" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://d.hatena.ne.jp/sirocco634/20100912#1284300126', '前回');" target="_blank">前回</a>までのところでは、「なんかリストを作るのが面倒くさいなぁ」と思ったのだが、よく考えたら quasi-quote を使えば問題ないことに気づく。こんな感じ:
</p>
<pre class="syntax-highlight">
<span class="synSpecial">(</span>use sxml.serializer<span class="synSpecial">)</span>
<span class="synSpecial">(</span>define gen-rss
<span class="synPreProc">`(</span><span class="synType">*TOP*</span>

<span class="synSpecial">(</span>define channel-example
<span class="synPreProc">`(</span>channel

<span class="synSpecial">(</span>description <span class="synConstant">&#34;Tumblr&#34;</span><span class="synSpecial">)</span>
<span class="synSpecial">(</span>lastBuildDate <span class="synConstant">&#34;Fri, 20 Jul 2007 19:00:00 +0900&#34;</span><span class="synSpecial">)</span>

<span class="synSpecial">(</span>define items-example

<p>
実行例はこんな感じになる:

<pre class="syntax-highlight">
