Logically, every class is exactly one nest. In the absence of Nest* attributes, the nest is a singleton. There are sometimes secondary reasons to distinguish an explicit singleton from an implicit one, reasons which don't affect member access control. The Lookup::in API wants to be sensitive the distinction in some way, so that it can use InnerClasses for old code, but ditch that in favor of NestMates in new code. We could ask reflection to show that distinction directly, or (maybe better) we could have Lookup::in grub it directly out of some secret channel. I'm on the fence about this. — John
