But does the LRM make this completely clear? Well, the LRM talks about "variables" as the actuals of ref formals. A very narrow interpretation would disallow any select (array, field, etc) but that seems overly restrictive. Allowing selects into unpacked aggregates seems to be the right balance. But no, the LRM is not clear about exactly what should be legal.
