Constructor of child class cannot pass arguments into parent constructor.
See the example:

class A{
 final this(int a=0){
  writeln(a);
 }
}
class B:A{
}

B b = new B(); //prints 0
B b2 = new B(2); //throws an error "expected 0 arguments, not 1..."

As we can see, logic is normal, but not in dmd. This bug creates a new bug:

class A{
 final this(int a=0){
  writeln(a);
 }
}
class B:A{
 this(int a=0){ //compiler perfectly, but parent constructor marked as "final"
  super(a);
 }
}

It might be not a hard problem, but it will be good for my project to create a
logical, nice-look code.
