The use of global data is "really" just a case of efficiently implemented
parameter passing.  We could see this clearly if we just considered the
characterization of parameter passing in terms of its operational semantics,
insteaed of full blown descriptive prescriptions.   It's just the difference
between what is "really happening" and how we see fit to describe and map
it.  Optimization can then be viewed as part of compiling, not programming.
