xpression's right
            operand is not parsed as a sub-expression and is seen as a single operand:
            the right operand is not developed further by the framework. Let's suppose
            <code class="computeroutput"><span class="identifier">op2</span></code> below has higher
            precedence than <code class="computeroutput"><span class="identifier">op1</span></code>,
            then
          </p>
<pre class="programlisting"><span class="identifier">a</span> <span class="identifier"
