Tie::RefHashSee the current Perl documentation for Tie::RefHash. Here is our local, out-dated (pre-5.6) version: Tie::RefHash - use references as hash keys
require 5.004; use Tie::RefHash; tie HASHVARIABLE, 'Tie::RefHash', LIST;
untie HASHVARIABLE;
This module provides the ability to use references as hash keys if you first tie the hash variable to this module.
It is implemented using the standard perl
TIEHASH interface. Please see the tie entry in
EXAMPLE
use Tie::RefHash; tie %h, 'Tie::RefHash'; $a = []; $b = {}; $c = \*main; $d = \"gunk"; $e = sub { 'foo' }; %h = ($a => 1, $b => 2, $c => 3, $d => 4, $e => 5); $a->[0] = 'foo'; $b->{foo} = 'bar'; for (keys %h) { print ref($_), "\n"; }
