To clarify, I'm talking about doing doing things by Object pointer or void  
pointer, which seems to work fine:

class Test {
	int a = 4;
	private int b = 5;
	void print(){ writeln(b); }
}

struct Test2 {
	int a = 4;
	private int b = 5;
	void print(){ writeln(b); }
}

void main()
{
	Test test = new Test;
	Object obj = test;
	int* b = cast(int*)(cast(void*)obj + Test.b.offsetof);
	*b = 1234;
	test.print();

	Test2 test2 = Test2();
	void *obj = &test2;
	int* b = cast(int*)(obj + Test2.b.offsetof);
	*b = 1234;
	test2.print();
}
