      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.

      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>
