I&#x27;m a bit confused. Shouldn&#x27;t this:<p><pre><code>    X&lt;b&gt; x;
</code></pre>
be this:<p><pre><code>    X&lt;B&gt; x;
</code></pre>
Or am I confusing things? Also, I assume the `&lt;&#x2F;b&gt;` at the end is a typo?<p>Furthermore, I wasn&#x27;t <i>even aware</i> you could access `a` the way it&#x27;s being accessed in the same example; I always use `this-&gt;a`. Actually, I&#x27;d access `x` through `this-&gt;x` anyway, in case there&#x27;s a lvar in the context. Although, I rarely write C++ anyway.
