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.
