It's not necessary in Ada 95 unless the components are aliased. I think
Robert uses too many aliased things, and thus has their restrictions on the
brain. :-)

(There is some hope that this restriction will be lifted in Ada 200Y,
because it doesn't really fix anything, and we're likely to adopt a
different solution to the problem that it was supposed to fix. But that's
TBD.)
