It is possible to construct tests with &a[0] or &a[1] - they just wouldn't 
exercise the new code paths.  Because &a[0] and &a[1] being handled is a 
feature which is untested, my point is that it would also be useful to add 
such tests to make sure that the subsequent changes in this area don't 
break that feature.
