At a minimum, you'd want to make first object aliased I'd think. I'm not sure
whether without that, you'd be guaranteed that some optimization techniques
wouldn't mess you up (register optimizations, etc.). Aliased at least lets the
compiler know that the object might be accessed via some alternate path, so it
will know not to do anything naughty to the object which might cause problems
with access via an alias. Maybe one of the compiler internals experts will weigh
in on this one.
