mparison operators are <code class="mendoza-code">=</code>, <code class="mendoza-code">&lt;</code>, <code class="mendoza-code">&lt;=</code>, <code class="mendoza-code">&gt;</code>,
<code class="mendoza-code">&gt;=</code>.  In the simple case, each operator can be used to compare two values
as follows: <code class="mendoza-code">(&lt; a b)</code> will return true if a &lt; b, and false otherwise.
Similarly <code class="mendoza-code">(= a b)</code> will be true only if a == b.
