From everything I've been reading, you can't tie hashrefs or listrefs, anyways. You could look at trying to tie a GLOB, but I have no idea how you'd go about doing that. And, as I'm typing this, I'm trying to figure it out and it's not looking good. *shrugs*

I'm also looking at possibly tying a hash and an array together ... but that's also not looking good. *shrugs*

Update: Check out my second response...
