Following should compile, but not.
(In comment, -> is superclass lookup, => is alias this lookup)
----
class A{ int a = 1; }
class B{ int b = 2; }
class C:A{
    B obj;
    alias obj this;
    this(){ obj = new B(); }
}
class X:C{  }
void main()
{
    auto c = new C();
    assert(c.a == 1);   // lookup C -> A, OK
    assert(c.b == 2);   // lookup C => B, OK

    auto x = new X();
    assert(x.a == 1);   // lookup X -> C -> A, OK
    assert(x.b == 2);   // lookup X -> C => B, NG (Line 17)
}
----
test.d(17): Error: no property 'b' for type 'test.X'
