It's okay, since this bug will never be fixed until someone can
explain why they believe making things non-addressable will result in
more aliasing, and not less.
I suspect the reality is there is some fundamental misunderstanding of
how aliasing or addressability works on the part of the Ada folks (no
offense to them, it's just the arguments they keep offering are, well,
strange to anyone who understands aliasing).
