Default values are properly set by the Action into their (Action)Parameters.

  • we changed the boost::preprocessor magic to accomplish this.
  • NODEFAULT -> NOPARAM_DEFAULT to be safe.
  • it has been a hell of a lot of work to make it possible to add a construct such as ", default" to the call of a function, either the comma or the default is easy but both could only be accomplished via a list contained in the sequence of default values. Because the list has an explicit NIL element which is taken as NOPARAM_DEFAULT.
  • PARAM_DEFAULT is a macro to wrap the default value into a list.
  • Property mode set to 100644
