<a name="idp475997296"></a><h2>Description</h2>
<p>This special concept enables various useful default behavior that makes any act like an ordinary object. By default any forwards all operations to the underlying type, and provides only the operations that are specified in its <code class="computeroutput">Concept</code>.</p>
<p>In detail, <a class="link" href="relaxed.html" title="Struct relaxed">relaxed</a> enables the following:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>A raw value can be assigned to an any. This will replace the value stored by the any. (But note that if <a class="link" href="assignable.html" title="Struct template assignable">assignable</a> is present, it takes priority.)</p></li>
<li class="listitem"><p>copy assignment of any uses the copy constructor if it can't use <a class="link" href="assignable.html" title="Struct template assignable">assignable</a> (either because <a class="link" href="assignable.html" title="Struct template assignable">assignable</a> is missing, or because the stored types do not match).</p></li>
<li class="listitem"><p>default construction of any is allowed and creates a null any.</p></li>
<li class="listitem"><p><a class="link" href="equality_comparable.html" title="Struct template equality_comparable">equality_comparable</a>: If the types do not match, it will return false.</p></li>
<li class="listitem"><p><a class="link" href="less_than_comparable.html" title="Struct template less_than_comparable">less_than_comparable</a>: If the types do not match, the ordering will be according to <code class="computeroutput">std::type_info::before</code>.</p></li>
<li class="listitem"><p>if the arguments to any other function do not match, it will throw a <a class="link" href="bad_function_call.html" title="Class bad_function_call">bad_function_call</a> exception instead of having undefined behavior. </p></li>
