Just want to verify this with the rest of the Monastery...

After some experimenting it seems that the best way to determine if two references are the same is to use the == operator: 

my $x = [];
my $y = [];

if ($x == $y) { print "x and y are the same reference\n" }
$y = $x;
if ($x == $y) { print "x and x are the same reference\n" }

This is better than using string equality (eq) since the references may have overridden stringification.

I couldn't find any explicit documentation for this, but it seems that evaluating a reference in numeric context returns the address of the reference which is how == works for determining reference equality.
