Reference Operations

• Since the stringized representation is faithful, you can use a hash to unstringize:

        sub remember {
          my ($reference) = @_;
          $true_value{$reference} = $reference;
        }

• The value is the real reference; the key is the stringized version

• To unstringize:

        sub unstringize {
          my ($stringized) = @_;
          return $true_value{$stringized};
        }
