| 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<>/smart pointer and |
| about relational operators. |
| </li> |
| <li class="listitem"> |
| 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. |
| </li> |
| <li class="listitem"> |
| Augustus Saunders also explored the different relational semantics between |
| optional<> and a pointer and developed the OptionalPointee concept |
| as an aid against potential conflicts on generic code. |
| </li> |
| <li class="listitem"> |
| Joel de Guzman noticed that optional<> can be seen as an API on top |
| of variant<T,nil_t>. |
| </li> |
| <li class="listitem"> |
| Dave Gomboc explained the meaning and usage of the Haskell analog to optional<>: |
| the Maybe type constructor (analogy originally pointed out by David Sankel). |
| </li> |
| <li class="listitem"> |
| Other comments were posted by Vincent Finn, Anthony Williams, Ed Brey, Rob |
| Stewart, and others. |
| </li> |
| <li class="listitem"> |
| Joel de Guzman made the case for the support of references and helped with |
| the proper semantics. |
| </li> |
| <li class="listitem"> |
| Mat Marcus shown the virtues of a value-oriented interface, influencing the |
| current design, and contributed the idea of "none". |
