Hi All
<div><br></div><div>I&#39;d appreciate some helpful words about Boost.Bind protect, &#39;cos I&#39;m not quite understanding it!</div><div><br></div><div>I thought its purpose was allow binding, but not evaluating, of a function object. So that this should</div>

<div>work.</div><div><br></div><div><div><font face="&#39;courier new&#39;, monospace">#include &lt;iostream&gt;</font></div><div><font face="&#39;courier new&#39;, monospace">#include &lt;boost/bind.hpp&gt;</font></div>

<div><br></div><div>Is it possible to have bind generate a fully bound, nullary callable object?</div><div><br></div><div>TIA,</div><div><br></div><div>- Rob.</div>
