<p>Post-formal review:</p>
<blockquote>
<p>William Kempf carefully considered the originally proposed interface
and suggested the new interface which is currently used. He also started
and fueled the discussion about the analogy optional&lt;&gt;/smart pointer
and about relational operators.<br>
Peter Dimov, Joel de Guzman, David Abrahams, Tanton Gibbs and Ian Hanson
focused on the relational semantics of optional (originally undefined);
concluding with the fact that the pointer-like interface doesn't make it
a pointer so it shall have deep relational operators.<br>
Augustus Saunders also explored the different relational
semantics between optional&lt;&gt; and a pointer and developed the
OptionalPointee concept as an aid against potential conflicts on generic code.<br>
Joel de Guzman noticed that optional&lt;&gt; can be seen as an
API on top of variant&lt;T,nil_t&gt;.<br>
Dave Gomboc explained the meaning and usage of the Haskell analog to optional&lt;&gt;:
the Maybe type constructor (analogy originally pointed out by David Sankel).<br>
Other comments were posted by Vincent Finn, Anthony Williams, Ed Brey, Rob Stewart,
and others.<br>
Joel de Guzman made the case for the support of references and helped with the
proper semantics.</p>

Mat Marcus shown the virtues of a value-oriented interface, influencing the
current design, and contributed the idea of &quot;none&quot;.</p>
