Nice start! It looks like there's still a lot of work to do, though.
One simple case that doesn't work:
struct {int x,*y;} z[] = {[0].x = 2, &z[0].x};
I think this indicates a rather serious error in the way you're doing
the recursion.
Do you have any thoughts on how to implement CodeGen without
duplicating all the designator logic?
