7495	Support for boost::optional in boost::program_options	Dmitry Trifonov <user61a@…>	Vladimir Prus	"It would be nice to allow support for boost::optional<T> arguments in program_options, so you can write following:

{{{
#!div style=""font-size: 100%""
  {{{#!cpp
optional<std::string> optionalArg;
options_description   desc(""allowed options"");
desc.add_options() (""optional"", value(&optionalArg), ""specify optional argument"");
  }}}
}}}

And shouldn't bother with argument checking using variables_map.
