It's at sw-eng.falls-church.va.us in directory
public/adaic/docs/standard/95lrm_rat/v6.0.

Yes.

Correct. It is not the Rationale.
AARM-6.5(24.d) just says:
24.d A function now creates an anonymous object. This is necessary
so that controlled types will work.
I.e. it wasn't intended as a "big deal" and the fact that you can rename
function results as constant objects was a handy side effect, but not
the original purpose.
The AARM is boring and useless for most folks. But if you want to know
in detail why Ada 95 is the way it is, or if you're a compiler writer,
the AARM is useful. It's filled with arcane trivia.
