Is this a bug?

strictly speaking, this is not a bug. compiler doesn't do deep analysis
on nested structures/classes to determine if they really require context
pointer. you can use `static class Inner` to tell the compiler that
`Inner` doesn't require any context.


To expand on this, nested classes (that is, a class nested inside 
another class) REQUIRE a pointer to the outer class instance (accessed 
via hidden member outer). The reason for this is Java portability. 
Seriously :)
