Codex just picks it up. The surface is basically a guarded object model, so pandas/polars-style operations stay close to the APIs the model already knows. There's some extra-tricks but they're probably out of scope for an HN comment.
In practice, Pandas/Polars API would lower to:
proxy -> attr("iloc") -> getitem(slice(1,10,None))
