yeah, totally, I can see that. I think that polars is the first library to do this locally, which is surprising if it has so many advantages.

It's been around in R-land for a while with dplyr and its variety of backends (including Arrow, the same as Polars). Pandas is just an incredibly mediocre library in nearly all respects.

Only for SQL databases, so not really. Source: have been running dplyr since 2011.

The Arrow backend does allow for lazy eval.
