Will do work through theses in order: 1. `Expr.rank()` 2. `DataFrame.with_row_index(order_by=...)` 3. `Expr.over(*partition_by, order_by=...)`
Already working, but should be able to optimize by passing `order_by` to `pc.RankOptions(sort_keys=...)` instead
Adapted from #3292
Pure stubs issue
- `DataFrame.sort` is a deviation from polars, which makes this a no-op - `with_row_index` already deviates from `polars` - This just ensures we always have a column for the lazy case
