Really glad to hear that! The graph can get complex for big notebooks and maintaining a full picture of variable dependencies across cells is a lot to ask a model to do correctly and hold in context. (It took us a little bit to get the parsing right in marimo!) With pair, it doesn't have to.

The model just "lives" in the environment, and when marimo says "you can't reuse that variable," it renames it and moves on. Hope you give pair a spin!
