I don't think I really have any questions, it's just that the way that
the qualifier is allowed at any layer is simply weird.  The one thing
I've considered that might make it a bit cleaner is always pulling the
attribute out to the outermost array/pointer type, and always pushing
it back in on a dereference, which would make the whole thing actually
work consistently.  Currently, there's an issue that for the two

__weak id* x;
id* __weak y;

The generated code for *x and *y is different.
