- These traits are all <span class="emphasis"><em>value traits</em></span>, which is to say the
- traits classes all inherit from <a class="link" href="../reference/integral_constant.html" title="integral_constant">integral_constant</a>,
- and are used to access some numerical property of a type. Often this is a
- simple true or false Boolean value, but in a few cases may be some other
- integer value (for example when dealing with type alignments, or array bounds:
- see <code class="computeroutput"><a class="link" href="../reference/alignment_of.html" title="alignment_of">alignment_of</a></code>,
- <code class="computeroutput"><a class="link" href="../reference/rank.html" title="rank">rank</a></code>
