>From "perldoc perlref":
Using a reference as a number produces an integer
representing its storage location in memory. The only useful thing to be
done with this is to compare two references numerically to see whether
they refer to the same location.
if ($ref1 == $ref2) { # cheap numeric compare of references
print "refs 1 and 2 refer to the same thing\n";
}
