I don't follow.  Global variables work that way, yes.  But that has nothing
to do with separate invocations of the program.  $^X is a global as well,
but does not work in the same way:

print $^X;
print $^O;
$^X = $^O = 'aaa';

This will print "MacPerlMacOS" the first time around.  Every following time
it is invoked in that session of the MacPerl app (i.e., without restarting
the app), it prints "MacPerlaaa".
