Dear Monks,
I have a database table with two column, either of them is unique. Now I need to lookup values both ways: 
$a = $a{ $b };
$b = $b{ $a };

[download]
I am looking for a decent datastructure to do this that will be less heavyweight than a object but more efficient than storing the table in two separate hashes.

Cheers,
