I think you just need to have polars installed; doesn't show up when I R CMD check --as-cran

Hmm... do we have different polars installed? Note that polars was archived on CRAN on 2023-07-18 (https://github.com/pola-rs/r-polars). I installed it from R-Universe following instructions on https://github.com/pola-rs/r-polars#install.

I have:

> packageVersion("polars")
[1] '0.8.1.9000'

> library(polars)
> ls(match("package:polars", search()), all.names = TRUE)
[1] ".pr"                  "as_polars_series"     "knit_print.DataFrame"
[4] "pl"

Looking at https://github.com/pola-rs/r-polars/blob/main/NAMESPACE, there's no csv_reader object exported.

yep - I had an older r-universe installation, before they put all public functions behind the pl environment.
polars::csv_reader() is now polars::pl$read_csv()

Had to add attachNamespace("polars") for polars::pl$read_csv() to work in rtemis::read(), don't know if there's a better way, will try later.
