I think maybe I've misunderstood the problem.  Are we talking about default 
values _of the function pointer_ or that get passed to the function pointer?

i.e. are we talking about,

     int foo(int delegate() dg = &bar) {
         ...
     }

or about

     int foo(int delegate() dg = &bar) {
         bar();  // assumes default arguments for bar
     }

...?
