I believe that you must supply all arguments on a function you define. Only
built-in functions can have optional parameters AFAIK.
If your intention is to be able to have a default substituted in a function for
missing arguments, then I would pass a null for each parameter to be defaulted.
That way, at the beginning of your function, you could write something like:
if( isNull( optionalD ) ) { optionalD = defaultValueD; }
