<p>Evaluates to <code class="computeroutput"><a class="link" href="strict_get.html" title="Function strict_get">strict_get</a></code> if <code class="computeroutput">BOOST_VARIANT_USE_RELAXED_GET_BY_DEFAULT</code>

<p><span class="bold"><strong>Recomendation</strong></span>: Use
          <code class="computeroutput"><a class="link" href="get_idp777944992.html" title="Function get">get</a></code> in new code without defining
          <code class="computeroutput">BOOST_VARIANT_USE_RELAXED_GET_BY_DEFAULT</code>. In that way <code class="computeroutput"><a class="link" href="get_idp777944992.html" title="Function get">get</a></code>
          provides more compile time checks and its behavior is closer to <code class="computeroutput">std::get</code>
