Hey guys,
I got a problem with the following code:

void main()
{
	struct SomeStruct
	{
		int aa;
	}

	class SomeClass
	{
		int a;

		SomeStruct foo()
		{
			SomeStruct m;
			m.aa=a;
			return m;
		}
	}

	SomeClass inst=new SomeClass();
	inst.foo.aa=20;

	assert(inst.a==20);
}


How can I make D set the member variable 'a' of SomeClass via this construction to another value? And what's with using "ref SomeStruct foo() {}"?

Thanks in advance!

Umm.. A shot in the dark?

void main(){
   struct SomeStruct{
      int* p;
      void aa(int a){
        *p = a;
      }
   }
   class SomeClass{
      int a;
      SomeStruct foo(){
         SomeStruct m;
         m.g = &a;
         return m;
      }
   }
   SomeClass inst = new SomeClass;
   inst.foo.aa = 20;
   assert(inst.a == 20);
}
