There's another potential problem with the "A.others" syntax.
Unless the rules were defined carefully, or unless Randy and company
decide that record components are covered by Atomic, it could result
in a partial read of A instead of a full read, and we could be back
to the ldr/ldrb saga once again. :-)

"And" is far better than "then" here but I think something that says
up front (before the components) that this is a partial aggregate
would be even more readable.
