Why `foo.x.saa.aa` and `foo.y.saa.aa` is the same? `shared_AA.saa` should still be instance variable, not class variable, right?

When you specify an initializer like this, that instance of 
``shared_AA_class`` gets put into the .init of ``shared_AA``.

It is shared between instances, even if its a field.

```d
import std.stdio;

struct Foo {
     ubyte value = 2;
}

void main() {
     writeln(cast(ubyte[])__traits(initSymbol, Foo)); // [2]
}
```
