You must keep the signatures as they are currently (default argument or not 
does not matter). But you can add methods, you can also add methods with the 
same name but different signature.

For if there is 
void foo(A a, B b, C c=C())
you can keep it and add
void foo(A a, B b, D d=D(), C c=C())

In the implementation, of course, you implement the first one by calling the 
second one.
