Hi chet,
you're right, it has no practical effect - rather esthetical. If I'm 
calculating it well the case should contain more than 536870912 
variables (2^32/8).
I have no access to 32-bit machine right now, but I can try to run 
following script:

for ((i=0; i<$((2**32/8 +1)); i++))
do
  eval "a$i=a$i"
done
