Ah, but as we are always fond of saying in this group "that's an
implementation detail, and not part of the language definition".  The
model where a compiler is "keeping notes about it in Narnia" is also
perfectly valid. However, RAM is easier to find than magic wardrobes,
so the "notes" are usually kept in RAM these days.
