... better to leave it up to the caller to decide if unstable sort order is acceptable for their usage
Actually, re-reading the example... the set is being provided to set_intersection
, it isn't the root expression. Hmm... Let me think about that - it may not be so unreasonable that way round, though I believe there will still be element-order instability in some of the other set-function results, which I don't think we want in what are still list-namespace ops (and special-casing this method over the others would feel a bit inconsistent 🤔). Need to check what we're currently doing here in terms of stability.

I don't think we should. It are set
operations done on "lists", not on "sets". Polars doesn't have a set type and making an exception for 1 expression is not something the IR should deal with.
