You know, there is a lot of good ideas posted already, but in your situation, I'd probably just pass around a hash full of objects. You could probably tie the hash to a meta_new that tries to create your object if it doesn't already exist, I suppose.

Whenever I catch myself passing a bunch of the same arguments to myriad subs, I stuff em into a hash and just pass it around.
