Comment (by rleigh_at_[hidden]):

 This is a feature I would also find most useful.  In my case, I would
 like to have an option:

   --run-session

 but also allow the user to specify an optional session name

   --run-session=session-name

 and if this is missing, I will compute one automatically.

 GNU getopt_long has the concept of "required" and "optional" arguments.
 It would be nice if typed_value/value_semantic had an optional() method
 and member to permit this.

 Roger
