<pre>Indexed accessor property not supported correctly
in clang "4.2.1 Compatible Clang 3.8.0 (trunk)"
-------------------------------------------------
// See: <a href="https://msdn.microsoft.com/en-us/library/yhfk0thd.aspx">https://msdn.microsoft.com/en-us/library/yhfk0thd.aspx</a>
// __declspec(property(get=GetX, put=PutX)) int x[];
// The above statement indicates that x[] can be used with one or more
// array indices. In this case, i=p->x[a][b] will be turned into
// i=p->GetX(a, b), and p->x[a][b] = i will be turned into p->PutX(a, b, i);
