It seems to me that Ada's way of doing this is the least ugly of most languages.

Turn_On : declare
    T : Register_Info := Register;
begin -- Turn_On
    T.On := True;
    Register := T;
end Turn_On;

Show me any commonly used language that is less ugly than that.

I don't see that there is anything here that the ARG would want to take action 
on, especially given that Randy said they're only interested in things that are 
hard or impossible to do in Ada. This is clearly not hard or impossible.

Sometimes these devices have fields that have to have zero written to them, but 
might be non-zero when read. For those cases, Ada looks even better:

Turn_On : declare
    T : Register_Info := Register;
begin -- Turn_On
    Register := (On => True, Zork => T.Piffle, Elffip => T.Kroz, others => 0);
end Turn_On;
