That's why my message identified the sections that
were new.

Er, in frames.pdf, the pointer *doesn't* point to
{func,class}.  As section 15 makes clear with a
diagram, the cache item in a load_slot or store_slot
instruction points to something which is logically
{descriptor,offset} but can be stored more compactly.

As indeed section 15 already says.

It's from "Rite of Passage" by Alexei Panshin.
While in transit between The Ship and Grainau (?)
Mia Havero is told a story, and in the store the
good guy wins a fortune by asking the ogre this
riddle:
	What is not, never was, and never will be?

The answer is a mouse's nest in a cat's ear.
Rite is one of the *great* SF stories, and it has
dated very well.
