   of the standard meaning. often means that anyone may look at the sacred
   object, but clobbering it will screw whatever it is sacred to. the

   program would be interpreted by a hacker to mean that if any _other_
   part of the program changes the contents of register 7, dire
   consequences are likely to ensue.
