Hmmm. What I get from your post is that I really already know what I need to know. Most any modest set of operations will suffice, and everything else can be written in those terms. (get/set/size/insert/delete/concat is more than complete.)

Wow, I don't think I agree with that. I'd rather write joins and projects and restricts than have to write Java code for doing the same.

I guess I'm just nervous that I'm missing some clever formalism which will change my outlook on lists, which I'm beginning to get clear that I'm not.
