Consider the following code:

int x;
SS ss;

void main()

S s;
s.ss.y();

If I change `return x;` to `return this.x;` then of course it
emits the following error:
Error: no property `x` for type `SS`
My understanding is that `SS` should have a context pointer to
an instance of `S`, but how do I navigate the members of `S`
and `SS`. Is this a bug?
Thanks,

My understanding is that nested structs have an implicit
context pointer to their containing scope.
Nesting with hidden context pointer is only for nested structs
inside functions.

This is a source a confusion unfortunately.
