Hi Mandy,

Thanks for looking at this.

I would prefer to leave unmodified code completely unmodified to 
simplify the eventual code review when pushing to mainline. While such a 
comment may seem useful due to the way this issue arose, if we back up 
and view this as never-changed code, then commenting that it doesn't 
need to change seems unnecessary to me. There are numerous things that 
work unchanged with nestmates (specifically anything to do with inner 
classes attributes and existing enclosing class notions), and we won't 
want to add comments to them all.

Thanks,
David
