<p>
All the value based traits in this library conform to MPL's requirements for
an <a href="../../../../../libs/mpl/doc/refmanual/integral-constant.html" target="_top">Integral
Constant type</a>: that includes a number of rather intrusive workarounds
for broken compilers.

<p>
Purely as an implementation detail, this means that <code class="computeroutput"><a class="link" href="reference/integral_constant.html" title="integral_constant">true_type</a></code>
inherits from <a href="../../../../../libs/mpl/doc/refmanual/bool.html" target="_top"><code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">mpl</span><span class="special">::</span><span class="identifier">true_</span></code></a>,
<code class="computeroutput"><a class="link" href="reference/integral_constant.html" title="integral_constant">false_type</a></code>
